- Add support for OpenSSL 1.1.0 and newer versions in MSVC scripts
Michael Paquier: Up to now, the MSVC build scripts are able to support only one fixed version of OpenSSL, and they lacked logic to detect the version of OpenSSL a given compilation of Postgres is linking to (currently 1.0.2, the latest LTS of upstream which will be EOL'd at the end of 2019). This commit adds more logic to detect the version of OpenSSL used by a build and makes use of it to add support for compilation with OpenSSL 1.1.0 which requires a new set of compilation flags to work properly. The supported OpenSSL installers have changed their library layer with various library renames with the upgrade to 1.1.0, making the logic a bit more complicated. - Add toast-level reloption for vacuum_index_cleanup
Michael Paquier: a96c41f has introduced the option for heap, but it still lacked the variant to control the behavior for toast relations. While on it, refactor the tests so as they stress more scenarios with the various values that vacuum_index_cleanup can use. - Add pg_stats_ext view for extended statistics
Tomas Vondra: Regular per-column statistics are stored in pg_statistics catalog, which is however rather difficult to read, so we also have pg_stats view with a human-reablable version of the data. For extended statistic the catalog was fairly easy to read, so we did not have such human-readable view so far. - Add pg_dumpall --rows-per-insert
Alvaro Herrera: Commit 7e413a0f82c8 added that option to pg_dump, but neglected to teach pg_dumpall how to pass it along. - doc: PG 12 relnotes, add mention of single-child optimization
Bruce Momjian: Add mention of single-child optimization for partitions and UNION ALL. - Avoid spurious deadlocks when upgrading a tuple lock
Alvaro Herrera: When two (or more) transactions are waiting for transaction T1 to release a tuple-level lock, and transaction T1 upgrades its lock to a higher level, a spurious deadlock can be reported among the waiting transactions when T1 finishes. - doc: Add best practises section to partitioning docs
David Rowley: A few questionable partitioning designs have been cropping up lately around the mailing lists. - Fix operator naming in pg_trgm GUC option descriptions
Alexander Korotkov: Descriptions of pg_trgm GUC options have % replaced with %% like it was a printf-like format. - doc: Add links to tables
Peter Eisentraut: Formal tables should generally have an xref in the text that points to them. - pg_upgrade: Make test.sh's installcheck use to-be-upgraded version's bindir
Andres Freund: On master (after 700538) the old version's installed psql was used -even when the old version might not actually be installed / might be installed into a temporary directory.
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.
