Hello. We are running PostgreSQL 9.5.13 and we faced the very same issue as described in this thread: https://www.postgresql.org/message-id/B9BEA448-978F-4A14-A088-3FD82214FFAC%40pvv.ntnu.no Briefly, we have got heavy update/insert/truncate activities on many tables and we're noticed that autovacuum processes hold a lot of file descriptors to deleted data-files (in sum >300GB). The last answer from Tom Lane in that thread was: "So far, my guess is that this is fixed by commits a1f064fc2 + d7598aeea." Is there any patches/configuration recommendations to solve this problem yet? Thank you. -- Evgeniy Losev Senior System Administrator i-Digital
