Re: [PERFORM] Postgresql 8.4 optimize for heavy select load

2016-09-19 Thread julyanto SUTANDANG
You might wanted to upgrade to new  version 9.5 with small effort by using
pg_upgrade,
we have done upgrading and achieve more than 20x faster from 8.4 to 9.5 (it
depends on the type of sql statement actually)

We probably need to see schema and query examples to help you (with
EXPLAIN ANALYZE output). Also - err 8.4 - I (and others probably) will
recommend you upgrade to a more recent (and supported for that matter)
version - currently 9.5/9.6 - lots of performance improvements you are
missing out on!


Especially since 8.4 is out of support for 2 years:
