Re: Force a merge join?

OK, I posted the current schema and before and after EXPLAIN output.

The problem query is "select * from vtb_allocpayroll".  It is messy, but works fine until I analyze things...

I will look into the pg_stats thing I saw mentioned, but am not sure if it applies since I am way back at 7.1.3.

Yes, I'd be interested in seeing that, as well as the output of
EXPLAIN ANALYZE for both the good and bad query plans.
