It's necessary to make sure that owning tables have a relcache invalidation prior to advancing the command counter to make newly-entered catalog tuples for the index visible. inval.c must be able to maintain the consistency of the local caches in the event of transaction abort. There is usually only a problem when CREATE INDEX transactions abort, since there is a generic invalidation once we reach index_update_stats(). This bug is of long standing. Problems were made much more likely by the addition of parallel CREATE INDEX (commit 9da0cc35284), but it is strongly suspected that similar problems can be triggered without involving plan_create_index_workers(). (plan_create_index_workers() triggers a relcache build or rebuild, which previously only happened in rare edge cases.)

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.
