Yes, if you want multiple timeouts, you clearly could go in that direction.

I certainly would like _something_ that works in psql/libpq, and the simple SET QUERY_TIMEOUT does work for them. More sophisticated stuff probably should be done in the application or interface. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026 ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
