Do you mean that you don't see an Index being considered by planner in
Postgres, whereas a similar index is used in Oracle ?
If the above is yes, can you provide some more information?

Okay. You might have to provide some more information to get more help such
as, the SQL, it's Query Plan and Table DDL.
If you have migrated this table from Oracle, you might have to perform a
Vacuum Analyze on this table before you try anything.
Vacuum analyze <table>;

There are no query hints in Postgres to direct it to use a particular
index. Often it's the query itself that can be tuned to fix this happening
or the ideal plan is actually being used vs the index you think you expect
it should use.
Share the query plan and table structure and people might be able to help
you out more.
