recordMultipleDependencies had the wrong scope for its "version" variable, allowing a version label to leak from the collation entry it was meant for to subsequent non-collation entries. This is relatively hard to trigger because of the OID-descending order that the inputs will normally arrive in: subsequent non-collation items will tend to be pinned. But it can be exhibited easily with a custom collation. Also, don't special-case the default collation, but instead ignore pinned-ness of a collation when we've found a version for it. This avoids creating useless pg_depend entries, and removes a not-very- future-proof assumption that C, POSIX, and DEFAULT are the only pinned collations. A small problem is that, because the default collation may or may not have a version, the regression tests can't assume anything about whether dependency entries will be made for it. This seems OK though since it's now handled just the same as other collations, and we have test cases for both versioned and unversioned collations. Fixes oversights in commit 257836a75. Thanks to Julien Rouhaud for review. Discussion: https://postgr.es/m/3564817.1618420687@sss.pgh.pa.us
PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
