postgresql version 7.3.3 .conf params changed from defaults. shared_buffers = 64000 sort_mem = 64000 fsync = false effective_cache_size = 400000
ex. query: select * from x where id in (select id from y);
There's an index on each table for id. SQL Server takes <1s to return, postgresql doesn't return at all, neither does explain analyze.
x has 1200673 rows
y has 1282 rows
It seems like its ignoring the index and not using enough memory.. any ideas?
