Of course you can also see what the query plan will be without having to run the query through a standard explain query:

Does anyone know if it's possible to see the plan being executed by Postgres for an active sql statement (from pg_stat_activity). This is to be able to troubleshoot poor performing ones and in Oracle we are able to retrieve such a plan. Additionally, how do I see the actual sql statement that shows as "<unnamed portal x>". Thanks so much for any advice you all may have. -Dan Welcome...!!! You need to use additional module to write query plan in logs i.e., AUTO_EXPLAIN. http://www.postgresql.org/docs/9.2/static/auto-explain.html --- Regards, Raghavendra EnterpriseDB Corporation Blog: http://raghavt.blogspot.com/
