If you do a:

VACUUM FULL ANALYZE

Hi All -

 

               I have query in production and test. The tables in both the environment has the same structure ,indexes and constraints. But the in the test and the prod the explain plan is totally different. In test environment the query is taking long time and noticed that indexes are not being utilized ? I am not able to figure it  Can you please share your thoughts?

 

 

Regards
