A corrective release of the PostgreSQL 14.4 database has been formed, which fixes a serious problem that, under certain circumstances, can lead to unnoticed data corruption in indexes when executing the \"CREATE INDEX CONCURRENTLY\" and \"REINDEX CONCURRENTLY\" commands. Some records may not be accounted for in the indexes created with the specified commands, leading to omissions of specific rows when performing SELECT queries involving the problematic indexes. <\/p>\n

To determine the fact of B-tree index corruption, you can use the command \"pg_amcheck --heapallindexed database_name\". In case of error detection or if the commands \"CREATE INDEX CONCURRENTLY\" and \"REINDEX CONCURRENTLY\" were used in earlier releases with other types of indexes (GiST, GIN, etc.), it is recommended after updating to version 14.4 to perform reindexing using the utility \"reindexdb --all\" or the command \"REINDEX CONCURRENTLY index_name\". <\/p>\n

Only the 14.x branch is affected, which included optimizations that exclude certain transactions related to the execution of \"CREATE INDEX CONCURRENTLY\" and \"REINDEX CONCURRENTLY\" during the VACUUM operation. As a result of these optimizations, some tuples in the heap memory that were updated or truncated during index creation did not get included in the indexes created in \"CONCURRENTLY\" mode.
