Thanks for the report! Yes, that's possible. I'm thinking to disable autovacuum for the index which pg_clean_pending_list() is working on by setting autovacuum_enabled reloption when creating the table. Patch attached. This patch also sets gin_pending_list_limit reloption to 4MB, just to be safe, so that "make installcheck" will not fail even when gin_pending_list_limit GUC is very small. Barring objection, I'll push this patch. Regards, -- Fujii Masao
