My reaction was if you always put the pid in when updating the hint it might work out pretty well. When you finish you remove the hint iff the pid is your own. It has exactly the same properties you describe of leaving a small window with no hint when you finish a scan but only if you were the last to update the scan position which i would expect would be pretty rare except for the last scanner. If a backend died it would leave a scan position behind but the next scanner on that table would overwrite the pid and then remove it when it's finished. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
