Even cron'd scripts can run amok. Lock files are great as a CYA measure even if you're relatively certain there will be no opportunity for one copy to step on the next. I once had a cron'd script mail upper management every hour I was on vacation. You can imagine how long it was until I got another vacation request approved. ;) -- Steven Klassen - Lead Programmer Command Prompt, Inc. - http://www.commandprompt.com/ PostgreSQL Replication & Support Services, (503) 667-4564 ---------------------------(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
