There isn't such ID, but every table has an OID, an Object Identifier.

The (hidden) column "oid" of pg_class contains this OID.

I think, you don't need this, it is only for internal.

Thanks Andreas. Sorry for confusion here. I mean statement ID that can be associated with prepared query(not table) to improve performance of building query. I just need to find plan using statement ID and execute it. I don't know how to do this.
 
Thanks,
Jignesh

Please, answer to the list and not to me, and please try to avoid html and
top-posting.

I don't know if i understand you correctly. There isn't such an ID, but
you can look at pg_prepared_statements, this view contains name,
statement and other informations about all (currently) prepared
statements.

you can create a primary key to associate with each row in the table
