Re: Restore from online backup, query from pg_proc, got wrong result, please see the problem!

I did the followwing things to make a backup:
1.config the archive on
2. select * from pg_start_backup()
3.tar the $PTDATA dir to a package
4.select * from pg_stop_backup()

The followwing things to restore:
1.Unzip the tar package I packaged
2.Copy the archived XLOG fils to $PTDATA
3.pg_ctl start

Then did the staff I describe in the last mail.

Well, apparently you did the restore incorrectly, leading to an
inconsistent index on pg_proc.  Since you proided no details about how
you did that, it's hard to say more.
