Let me also add that on my old dual P3 550 256MB RAM -g significantly slowed down the build because linking took a long time, probably because it had to read in all those debug symbols for the link --- I remember the backend link taking quite a lot of time. In fact, even though I was debugging the backend regularly, I removed -g and added it only when I wanted to debug. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
