Hello again, we have another strange problem with autovacuum. The process goes well until it reaches the table pg_database (in some databases, not all), then it loops over it forever (until I run vacuum full analyze on that table, simple vacuum doesn't help): 2016-05-05 17:13:33 CEST 34818LOG: automatic vacuum of table "somedatabase.pg_catalog.pg_database": index scans: 0 pages: 0 removed, 233 remain tuples: 0 removed, 5817 remain, 0 are dead but not yet removable buffer usage: 87 hits, 0 misses, 0 dirtied avg read rate: 0.000 MB/s, avg write rate: 0.000 MB/s system usage: CPU 0.00s/0.00u sec elapsed 0.00 sec 2016-05-05 17:13:33 CEST 34819LOG: automatic vacuum of table "somedatabase.pg_catalog.pg_database": index scans: 0 pages: 0 removed, 233 remain tuples: 0 removed, 5817 remain, 0 are dead but not yet removable buffer usage: 87 hits, 0 misses, 0 dirtied avg read rate: 0.000 MB/s, avg write rate: 0.000 MB/s system usage: CPU 0.00s/0.00u sec elapsed 0.00 sec 2016-05-05 17:13:33 CEST 34820LOG: automatic vacuum of table "somedatabase.pg_catalog.pg_database": index scans: 0 pages: 0 removed, 233 remain tuples: 0 removed, 5817 remain, 0 are dead but not yet removable buffer usage: 87 hits, 0 misses, 0 dirtied avg read rate: 0.000 MB/s, avg write rate: 0.000 MB/s system usage: CPU 0.00s/0.00u sec elapsed 0.00 sec 2016-05-05 17:13:34 CEST 34821LOG: automatic vacuum of table "somedatabase.pg_catalog.pg_database": index scans: 0 pages: 0 removed, 233 remain tuples: 0 removed, 5817 remain, 0 are dead but not yet removable buffer usage: 87 hits, 0 misses, 0 dirtied avg read rate: 0.000 MB/s, avg write rate: 0.000 MB/s system usage: CPU 0.00s/0.00u sec elapsed 0.00 sec Not sure if it's a bug or I'm doing something wrong. Thanks in advance, Ondřej
