From b2e857eeaa9161aa4308df5158b8f11935cca977 Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Thu, 26 Sep 2024 21:06:49 +0900 Subject: [PATCH v1] reindexdb: Skip reindexing temporary tables and indexes. Reindexing temp tables or indexes of other sessions is not allowed. However, reindexdb in parallel mode previously listed them as the objects to process, leading to failures. This commit ensures reindexdb in parallel mode skips temporary tables and indexes by adding a condition based on the relpersistence column in pg_class to the object listing queries, preventing these issues. Note that this commit does not affect reindexdb when temporary tables or indexes are explicitly specified using the -t or -j options; reindexdb still does not skip them and can cause an error. Back-patch to v13 where parallel mode was introduced in reindexdb.
