There are bugs that might not bite you today, but may well in the future.

Are the queries you included the real ones or approximations? It looks like you have a bunch of seq scans happening. If they're all happening on the same table or small set of them, then a lot of queries should be able to access them in any order together in 8.3 Are sequential scans normal for this query when it runs fast? What does vmstat 10 and / or iostat -xd 10 have to say while this is running? -- To understand recursion, one must first understand recursion. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
