From 4081e6c1b3b4deb0760d17c6a0c81cc4e98f34c7 Mon Sep 17 00:00:00 2001 From: Baji Shaik Date: Sun, 11 Oct 2026 20:25:54 -0500 Subject: [PATCH v2] doc: say where autovacuum_max_parallel_workers can be set The parameter is PGC_SIGHUP, like the other autovacuum settings, but unlike them its description doesn't say it can only be set in postgresql.conf or on the server command line, nor that it can be overridden per-table. Add the usual sentence, matching the wording the other autovacuum parameters use for their table storage parameter. Backpatch to 19, where the parameter was added.
