If we're not executing a statement, we're probably trying to read() from the socket, and we'll notice if that returns 0 or -1. So it seems like we only need periodic checks while there's a statement in progress. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
