You might to take a look at the contrib module:
https://www.postgresql.org/docs/current/pgstatstatements.html
"The pg_stat_statements module provides a means for tracking planning and execution statistics of all SQL statements executed by a server."

Since he asked about execution plans, I was thinking auto_explain: https://www.postgresql.org/docs/current/auto-explain.html -- Bruce Momjian <bruce@momjian.us> https://momjian.us EDB https://enterprisedb.com Only you can decide what is important to you.
Thank you Adrian fir the reply, I am looking for something like complete execution plan of the function just like EXPLAIN does.

Hello Bruce,
I do not see parameters starting with auto_explain. in configuration file and also do I need to enable logging collector. Please guide me on this.
