Hi Team,

We are getting slowness after migration from oracle to Postgresql.
As checked in oracle function executed within 2 sec but same code taken time in Postgresql.
Index already applied, constraints already applied.
All configuration parameters was ok.
Cpu memory utilization everything was ok.
Please suggest what we should do.

Regards,
Vijay P Ingle

This is not a bug, you should rather use the pgsql-performance mailing
list (https://www.postgresql.org/list/pgsql-performance/).

When you'll do so, please also refer to
https://wiki.postgresql.org/wiki/Slow_Query_Questions to provide
enough information.
