Hi again,
I did this on the 7.3.1 database, and attached the output.
It actually ran faster after ANALYZE and 'set enable_mergejoin to off'
Thanks!
I also reloaded this database onto 7.3.4, tried the same query after
the ANALYZE, and the query executed a lot faster.
Thanks again!
I also attached the output of the EXPLAIN ANALYZE on 7.3.4
For now I'll maybe just disable mergejoin. But definitely a postgres
upgrade is what I will do.
I went through the different outputs of EXPLAIN ANALYZE a bit, and
I think I can now see where the difference is.
Thanks a lot for the help.
Regards
Stefan.
