Hello,
I am a newb in Postgres coming from Oracle. 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.
