I'm afraid I still don't get it. Let say I have an application that does `CREATE TEMP TABLE xx ; DROP TABLE xx` in every session all the time. Naturally there is not only one temp table per session. Could you explain please in more detail how exactly do these persistent rows help? -- Best regards, Aleksander Alekseev -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
