What do you mean by "early VACUUM"? Amit suggested disabling HOT-pruning, but HOT-pruning happens completely outside of VACUUM. It also happens inside VACUUM, so if we disabled HOT pruning, how could we VACUUM at all? Sorry, I am confused. Doesn't this issue also affected indexes on any unlogged table? -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
