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,

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.
