Other Activity This Week
- Still further rethinking of build changes for macOS Mojave
Tom Lane: To avoid the sorts of problems complained of by Jakob Egger, it'd be best if configure didn't emit any references to the sysroot path at all. - Improve tzparse's handling of TZDEFRULES ("posixrules") zone data
Tom Lane: In the IANA timezone code, tzparse() always tries to load the zone file named by TZDEFRULES ("posixrules"). - Back off using -isysroot on Darwin
Tom Lane: Rethink the solution applied in commit 5e2217131 to get PL/Tcl to build on macOS Mojave. - Add macro to cast away const without allowing changes to underlying type
Andres Freund: The new unconsitify(underlying_type, var) macro allows to cast constness away from a variable, but doesn't allow changing the underlying type. - Add missed tag in bloom.sgml
Alexander Korotkov: Backpatch commits don't contain this error. - Avoid duplicate XIDs at recovery when building initial snapshot
Michael Paquier: On a primary, sets of XLOG_RUNNING_XACTS records are generated on a periodic basis to allow recovery to build the initial state of transactions for a hot standby. - Doc: still further copy-editing for v11 release notes
Tom Lane: Justin Pryzby and myself.

Tom Lane: Justin Pryzby, Jonathan S. - Make an editing pass over v11 release notes
Tom Lane: Set the release date. - Correct attach/detach logic for FKs in partitions
Alvaro Herrera: There was no code to handle foreign key constraints on partitioned tables in the case of ALTER TABLE DETACH; and if you happened to ATTACH a partition that already had an equivalent constraint, that one was ignored and a new constraint was created.
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 In The Past Month
- doc: JIT is enabled by default in PG 12
Bruce Momjian: JIT was disabled by default in a PG 11 in a separate commit that will normally not appear in the PG 12 git logs. - Rework activation of commit timestamps during recovery
Michael Paquier: The activation and deactivation of commit timestamp tracking has not been handled consistently for a primary or standbys at recovery. - Sync our Snowball stemmer dictionaries with current upstream
Tom Lane: We haven't touched these since text search functionality landed in core in 2007 :-(. - Use ppoll(2), if available, to wait for input in pgbench
Tom Lane: Previously, pgbench always used select(2) for this purpose, but that's problematic for very high client counts, because select() can't deal with file descriptor numbers larger than FD_SETSIZE. - Remove absolete function TupleDescGetSlot().
Andres Freund: TupleDescGetSlot() was kept around for backward compatibility for user-written SRFs. - Add application_name to connection authorized msg
Stephen Frost: The connection authorized message has quite a bit of useful information in it, but didn't include the application_name (when provided), so let's add that as it can be very useful. Note that at the point where we're emitting the connection authorized message, we haven't processed GUCs, so it's not possible to get this by using log_line_prefix (which pulls from the GUC). - Add pg_ls_archive_statusdir function
Michael Paquier: This function lists the contents of the WAL archive status directory, and is intended to be used by monitoring tools. - Add pg_ls_tmpdir function
Michael Paquier: This lists the contents of a temporary directory associated to a given tablespace, useful to get information about on-disk consumption caused by temporary files used by a session query. - Improve the accuracy of floating point statistical aggregates
Dean Rasheed: When computing statistical aggregates like variance, the common schoolbook algorithm which computes the sum of the squares of the - Remove no-longer-needed variant expected regression result files
Tom Lane: numerology_1.out and float8-small-is-zero_1.out differ from their base files only in showing plain zero rather than minus zero for some results.
