Hello, In my log files I have an error that occurs frequently : FATAL: could not read from statistics collector pipe and FATAL: could not write to statistics collector pipe: No connection could be made because the target machine actively refused it. The server release is 8.0.3 and is running on WinXP Pro sp2 The pg_autovacuum deamon is running (if it can help...) I would appreciate any help. I wonder if this error is really "FATAL" or not. ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
