Please help Looks to me like your biggest problem is right here: " -> Seq Scan on subs s (cost=0.00..5599.42 rows=58313 width=69) (actual time=409.370..153354.835 rows=146954 loops=1)" " Filter: (CASE WHEN ((status = 0) AND issubsexpired(subsno)) THEN 15 ELSE status END <= 15)" 1ms/row is pretty slow, so I'm guessing that the issubsexpired() function is not too speedy. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
