- psql tab completion for CREATE DATABASE ... TEMPLATE ... Sehrope Sarkuni, reviewed by Merlin Moncure & Vitaly Burovoy with some editing by me http://git.postgresql.org/pg/commitdiff/52803098ab26051c0c9802f3c19edffc90de8843
- Fix recent commit for tab-completion of database template. The details of commit 52803098ab26051c0c9802f3c19edffc90de8843 were based on a misunderstanding of the role inheritance allowing use of a database for a template. While the CREATEDB privilege is not inherited, the database ownership is privileges are. Pointed out by Vitaly Burovoy and Tom Lane. Fix provided by Tom Lane, reviewed by Vitaly Burovoy. http://git.postgresql.org/pg/commitdiff/63c1a871940c7c4798788e98fdb1a24408a49d05

- Raise max setting of checkpoint_timeout to 1d. Previously checkpoint_timeout was capped at 3600s New max setting is 86400s = 24h = 1d Discussion: email@example.com http://git.postgresql.org/pg/commitdiff/c3c0d7bd701dae4737c974a59ffa9b366110f9c1
- Identify walsenders in pg_stat_activity. Following 8299471c37fff0b walsender procs are now visible in pg_stat_activity. Set query to â€˜walsenderâ€™ for walsender procs to allow them to be identified.

Peter Eisentraut pushed:
- pg_basebackup: Clean created directories on failure. Like initdb, clean up created data and xlog directories, unless the new -n/--noclean option is specified. Tablespace directories are not cleaned up, but a message is written about that. Reviewed-by: Masahiko Sawada <firstname.lastname@example.org> http://git.postgresql.org/pg/commitdiff/9083353b15c3cf8e7bbac104a81ad42281178cdf
- Add overflow checks to money type input function. The money type input function did not have any overflow checks at all. There were some regression tests that purported to check for overflow, but they actually checked for the overflow behavior of the int8 type before casting to money. Remove those unnecessary checks and add some that actually check the money input function.

Tom Lane pushed:
- Docs: assorted minor cleanups. Standardize on "user_name" for a field name in related examples in ddl.sgml; before we had variously "user_name", "username", and "user". The last is flat wrong because it conflicts with a reserved word. Be consistent about entry capitalization in a table in func.sgml. Fix a typo in pgtrgm.sgml. Back-patch to 9.6 and 9.5 as relevant. Alexander Law http://git.postgresql.org/pg/commitdiff/42fd984c0b7b53d1bc961c9ed6bb84fe28eae52b
- Fix executor/README to reflect disallowing SRFs in UPDATE. The parenthetical comment here is obsoleted by commit a4c35ea1c. Noted by Andres Freund. http://git.postgresql.org/pg/commitdiff/fdc79e1909dc3866a385ffb74bdd6ce6a082a300
- Improve parser's and planner's handling of set-returning functions. Teach the parser to reject misplaced set-returning functions during parse analysis using p_expr_kind, in much the same way as we do for aggregates and window functions (cf commit eaccfded9). While this isn't complete (it misses nesting-based restrictions), it's much better than the previous error reporting for such cases, and it allows elimination of assorted ad-hoc expression_returns_set() error checks. We could add nesting checks later if it seems important to catch all cases at parse time. There is one case the parser will now throw error for although previous versions allowed it, which is SRFs in the tlist of an UPDATE. That never behaved sensibly (since it's ill-defined which generated row should be used to perform the update) and it's hard to see why it should not be treated as an error. It's a release-note-worthy change though. Also, add a new Query field hasTargetSRFs reporting whether there are any SRFs in the targetlist (including GROUP BY/ORDER BY expressions). The parser can now set that basically for free during parse analysis, and we can use it in a number of places to avoid expression_returns_set searches. (There will be more such checks soon.) In some places, this allows decontorting the logic since it's no longer expensive to check for SRFs in the tlist --- so I made the checks parallel to the handling of hasAggs/hasWindowFuncs wherever it seemed appropriate. catversion bump because adding a Query field changes stored rules. Andres Freund and Tom Lane Discussion: <firstname.lastname@example.org> http://git.postgresql.org/pg/commitdiff/a4c35ea1c2f05dd5b56739fcd0dc36a4870ea0c0
- Be pickier about converting between Name and Datum. We were misapplying NameGetDatum() to plain C strings in some places. This worked, because it was just a pointer cast anyway, but it's a type cheat in some sense. Use CStringGetDatum instead, and modify the NameGetDatum macro so it won't compile if applied to something that's not a pointer to NameData. This should result in no changes to generated code, but it is logically cleaner. Mark Dilger, tweaked a bit by me Discussion: <EFD8AC94-4C1F-40C1-A5EA-304080089C1B@gmail.com> http://git.postgresql.org/pg/commitdiff/55c3391d1e6a201b5b891781d21fe682a8c64fe6
- Tweak targetlist-SRF tests. Add a test case showing that we don't support SRFs in window-function arguments. Remove a duplicate test case for SRFs in aggregate arguments. http://git.postgresql.org/pg/commitdiff/a163c006ca3e6026546ee0f6c487a0dcfc66f82b
- Tweak targetlist-SRF tests some more. Seems like it would be good to have a test case documenting the existing behavior for non-top-level SRFs. http://git.postgresql.org/pg/commitdiff/0dac5b5174bde3d6fb4b444a2aa4ca1f0091e258
- Make min_parallel_relation_size's default value platform-independent. The documentation states that the default value is 8MB, but this was only true at BLCKSZ = 8kB, because the default was hard-coded as 1024. Make the code match the docs by computing the default as 8MB/BLCKSZ. Oversight in commit 75be66464, noted pursuant to a gripe from Peter E. Discussion: <email@example.com> http://git.postgresql.org/pg/commitdiff/5472ed3e9bc23eff0b4e457fe564ac667cb69441
- Add debugging aid "bmsToString(Bitmapset *bms)". This function has no direct callers at present, but it's convenient for manual use in a debugger, rather than having to inspect memory and do bit-counting in your head. In passing, get rid of useless outBitmapset() wrapper around _outBitmapset(); let's just export the function that does the work. Likewise for outToken(). Ashutosh Bapat, tweaked a bit by me Discussion: <CAFjFpRdiht8e1HTVirbubr4YzaON5iZTzFJjq909y4sU8M_6eA@mail.gmail.com> http://git.postgresql.org/pg/commitdiff/d8c61c9765339351409f06bbf964dcb8c1929e8b
Andres Freund pushed:
- Add more tests for targetlist SRFs. We're considering changing the implementation of targetlist SRFs considerably, and a lot of the current behaviour isn't tested in our regression tests. Thus it seems useful to increase coverage to avoid accidental behaviour changes. It's quite possible that some of the plans here will require adjustments to avoid falling afoul of ordering differences (e.g. hashed group bys). The buildfarm will tell us. Reviewed-By: Tom Lane Discussion: <firstname.lastname@example.org> http://git.postgresql.org/pg/commitdiff/bfe16d1a5dec0d23c917c37de646256c71e07ee8
- Address portability issues in bfe16d1a5 test output. http://git.postgresql.org/pg/commitdiff/9f478b4f19d8e26300ae19e42c26343f5791e32a
- Remove user_relns() SRF from regression tests. The output of the function changes whenever previous (or, as in this case, concurrent) tests leave a table in place. That causes unneeded churn. This should fix failures due to the tests added bfe16d1a5, like on lapwing, caused by the tsrf test running concurrently with misc. Those could also have been addressed by using temp tables, but that test has annoyed me before.

Robert Haas pushed:
- Have heapam.h include lockdefs.h rather than lock.h. lockdefs.h was only split from lock.h relatively recently, and represents a minimal subset of the old lock.h. heapam.h only needs that smaller subset, so adjust it to include only that. This requires some corresponding adjustments elsewhere. Peter Geoghegan http://git.postgresql.org/pg/commitdiff/445a38aba26cb80a4506af2248e3b425f795a099
- Improve code comment for GatherPath's single_copy flag. Discussion: firstname.lastname@example.org http://git.postgresql.org/pg/commitdiff/6415ba502bdc540e21f122d4c6c87d4a35f8ec27
- pg_buffercache: Allow huge allocations. Otherwise, users who have configured shared_buffers >= 256GB won't be able to use this module. There probably aren't many of those, but it doesn't hurt anything to fix it so that it works. Backpatch to 9.4, where MemoryContextAllocHuge was introduced. The same problem exists in older branches, but there's no easy way to fix it there. KaiGai Kohei http://git.postgresql.org/pg/commitdiff/8a503526e455b981718c2d24bd1630fd5b4cf7ac
- Fix typo in comment. Amit Langote http://git.postgresql.org/pg/commitdiff/ffccee473682ed18a27d667b7a4f45d802dd61c4
- Clarify policy on marking inherited constraints as valid. Amit Langote and Robert Haas http://git.postgresql.org/pg/commitdiff/5225c66336a1e4b46925e9f169086fc70f49736f
Heikki Linnakangas pushed:
- Fix and clarify comments on replacement selection. These were modified by the patch to only use replacement selection for the first run in an external sort. http://git.postgresql.org/pg/commitdiff/c99dd5bfed23d9787dcf7d00197c1ed42bcfdb02
- Support OpenSSL 1.1.0. Changes needed to build at all: - Check for SSL_new in configure, now that SSL_library_init is a macro. - Do not access struct members directly. This includes some new code in pgcrypto, to use the resource owner mechanism to ensure that we don't leak OpenSSL handles, now that we can't embed them in other structs anymore. - RAND_SSLeay() -> RAND_OpenSSL() Changes that were needed to silence deprecation warnings, but were not strictly necessary: - RAND_pseudo_bytes() -> RAND_bytes(). - SSL_library_init() and OpenSSL_config() -> OPENSSL_init_ssl() - ASN1_STRING_data() -> ASN1_STRING_get0_data() - DH_generate_parameters() -> DH_generate_parameters() - Locking callbacks are not needed with OpenSSL 1.1.0 anymore. (Good riddance!) Also change references to SSLEAY_VERSION_NUMBER with OPENSSL_VERSION_NUMBER, for the sake of consistency. OPENSSL_VERSION_NUMBER has existed since time immemorial. Fix SSL test suite to work with OpenSSL 1.1.0. CA certificates must have the "CA:true" basic constraint extension now, or OpenSSL will refuse them. Regenerate the test certificates with that. The "openssl" binary, used to generate the certificates, is also now more picky, and throws an error if an X509 extension is specified in "req_extensions", but that section is empty. Backpatch to all supported branches, per popular demand. In back-branches, we still support OpenSSL 0.9.7 and above. OpenSSL 0.9.6 should still work too, but I didn't test it. In master, we only support 0.9.8 and above. Patch by Andreas Karlsson, with additional changes by me. Discussion: <20160627151604.GD1051@msg.df7cb.de> http://git.postgresql.org/pg/commitdiff/593d4e47db7af1a3a5dd6b6b1971f181b5566dbd
- Fix building with LibreSSL. LibreSSL defines OPENSSL_VERSION_NUMBER to claim that it is version 2.0.0, but it doesn't have the functions added in OpenSSL 1.1.0. Add autoconf checks for the individual functions we need, and stop relying on OPENSSL_VERSION_NUMBER. Backport to 9.5 and 9.6, like the patch that broke this. In the back-branches, there are still a few OPENSSL_VERSION_NUMBER checks left, to check for OpenSSL 0.9.8 or 0.9.7. I left them as they were - LibreSSL has all those functions, so they work as intended. Per buildfarm member curculio. Discussion: <email@example.com> http://git.postgresql.org/pg/commitdiff/5c6df67e0c961f68e73e7c1e6312211ed59da00a
- Fix ecpg -? option on Windows, add -V alias for --version. This makes the -? and -V options work consistently with other binaries. --help and --version are now only recognized as the first option, i.e. "ecpg --foobar --help" no longer prints the help, but that's consistent with most of our other binaries, too. Backpatch to all supported versions.
