If I have a process which is inserting/updating tuples and run a vacuum while that process is going, will the vacuum wait for the process to finish? Or, will I have a problem with the db? How about the other way: doing a insert/update while a vacuum is running? Thanks. -Tony ---------------------------(end of broadcast)--------------------------- TIP 3: 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
