I am having a problem with having idle sessions in transactions. In pgAdmin Server Status, it is showing "RELEASE_EXEC_SVP_XXXXXX" (XXXXXX data are varied) as its query and it's locks also contain a lot of these "RELEASE_EXEC_SVP_XXXXXX" entries. What do these mean? These commonly cause lock blocking problems because these sessions sometimes lock other rows but the session status is always "Idle in transaction". I do not know why there are sessions like these. I have reviewed our system and do not see any possibility of transactions getting started that are not rollbacked or committed and just stay idle so this must be something internal to postgresql. Version of PostgreSQL is 9.2.8 running on Windows using psqlodbc driver 9.0.3.210.
From the psqlodbc source this would seem to indicate SAVEPOINTs are involved, so you might want to take a look at this thread:
