Magnus, thank you. How about the main problem: I have two commands like CREATE TEMP TABLE tasutud1 (dokumnr INTEGER PRIMARY KEY, tasutud NUMERIC(1)) ON COMMIT DROP; in my transaction. This command causes NOTICE message written to the log file. There a number of transactions per second. So Postgres writes number notice messages in every second. I don't see any reason for writing notice messages in this case. Small ON COMMIT DROP table will never written to disk, it exists only during transaction. It is not reasonable to write information about Postgres internal temporary memory structures to log. Can you apply a patch which disables NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index messages at all or at least for temporary tables, please ?
