Recent Activity
- Track new configure flags introduced for version 11 in pg_config.h.win32
Michael Paquier: The following set of flags mainly matter when building Postgres code with MSVC and those have been forgotten with latest developments: - HAVE_LDAP_INITIALIZE, added by 35c0754f, and marked as disabled. - Fix a couple of bugs with replication slot advancing feature
Michael Paquier: A review of the code has showed up a couple of issues fixed by this commit:- Physical slots have been using the confirmed LSN position as a start comparison point which is always 0/0, instead use the restart LSN position (logical slots need to use the confirmed LSN position, which was correct).- The actual slot update was incorrect for both physical and logical slots. - Fix simple_prompt() to disable echo on Windows when stdin != terminal
Tom Lane: If echo = false, simple_prompt() is supposed to prevent echoing the input (for password input). - doc: PG 11 release notes, add third author
Bruce Momjian - Detoast plpgsql variables if they might live across a transaction boundary
Tom Lane: Up to now, it's been safe for plpgsql to store TOAST pointers in its variables because the ActiveSnapshot for whatever query called the plpgsql function will surely protect such TOAST values from being vacuumed away, even if the owning table rows are committed dead. - Add a script and a config file to run perlcritic
Andrew Dunstan: This is similar to what we do to run perltidy. - Release notes for 10.4, 9.6.9, 9.5.13, 9.4.18, 9.3.23.
Tom Lane - First-draft release notes for 10.4.
Tom Lane: As usual, the release notes for other branches will be made by cutting these down, but put them up for community review first. - Re-think predicate locking on GIN indexes
Teodor Sigaev: The principle behind the locking was not very well thought-out, and not documented. - Add HOLD_INTERRUPTS section into FinishPreparedTransaction
Teodor Sigaev: If an interrupt arrives in the middle of FinishPreparedTransaction and any callback decide to call CHECK_FOR_INTERRUPTS (e.g.
PostgreSQL Release Tags
- Automate the maintenance of SO_MINOR_VERSION for our shared libraries
Tom Lane: Up to now we've manually adjusted these numbers in several different Makefiles at the start of each development cycle. - Advance PG_CONTROL_VERSION.
Tom Lane: This should have been done in commit 73c986adde5d73a5 which added several new fields to pg_control, and again in commit 5028f22f6eb05798 which changed the CRC algorithm, but it wasn't. - Tab complete CREATE EXTENSION .. VERSION.
Robert Haas: Jeff Janes - Bump PG_CONTROL_VERSION for previous 9.4 changes
Tom Lane: This should have been done in 6bc8ef0b7f1f1df3998745a66e1790e27424aa0c and/or 50e547096c4858a68abf09894667a542cc418315, but better late than never.
Most Popular This Year
- Basic JIT provider and error handling infrastructure
Andres Freund: This commit introduces: 1) JIT provider abstraction, which allows JIT functionality to be implemented in separate shared libraries. - Add polygon opclass for SP-GiST
Teodor Sigaev: Polygon opclass uses compress method feature of SP-GiST added earlier. - Add support for ICU 4.2
Peter Eisentraut: Supporting ICU 4.2 seems useful because it ships with CentOS 6. Versions before ICU 4.6 don't support pkg-config, so document an installation method without using pkg-config. In ICU 4.2, ucol_getKeywordsForLocale() sometimes returns values that will not be accepted by uloc_toLanguageTag(). - Support huge pages on Windows
Magnus Hagander: Add support for huge pages (called large pages on Windows) to the Windows build. - Add parallel-aware hash joins
Andres Freund: Introduce parallel-aware hash joins that appear in EXPLAIN plans as Parallel Hash Join with Parallel Hash. - Add current directory to Perl include path
Peter Eisentraut: Recent Perl versions don't have the current directory in the module include path anymore, so we need to add it here explicitly to make these scripts continue to work. - Add hash partitioning
Robert Haas: Hash partitioning is useful when you want to partition a growing data set evenly. - Add support for Motorola 88K to s_lock.h
Tom Lane: Apparently there are still people out there who care about this old architecture. - Support Parallel Append plan nodes
Robert Haas: When we create an Append node, we can spread out the workers over the subplans instead of piling on to each subplan one at a time, which should typically be a bit more efficient, both because the startup cost of any plan executed entirely by one worker is paid only once and also because of reduced contention. - Allow UPDATE to move rows between partitions
Robert Haas: When an UPDATE causes a row to no longer match the partition constraint, try to move it to a different partition where it does match the partition constraint.
