Are you sure you did "VACUUM FULL pg_attribute" on Aug 7, could you please confirm that free_percent arises from 0 to 92% in one day? Do you have some processes that intensively create tables or columns and then delete them or create them in transaction and rollback the transaction? -- Kind regards, Sergey Konoplev PostgreSQL Consultant and DBA http://www.linkedin.com/in/grayhemp +1 (415) 867-9984, +7 (901) 903-0499, +7 (988) 888-1979 gray...@gmail.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
