Well, I have to disclaim credit/blame for this, because Red Hat has
never shipped PG 8.3.anything for RHEL-5. Possibly the OP is running
Devrim's or Command Prompt's RPMs. That said, the initscript Devrim
uses looks just about like mine, and there's no chance whatever that it
would selectively delete portions of what's under $PGDATA. I have to
think that there's a loose cannon somewhere else in the OP's system.
We have for example seen some very unfortunate behavior in the past
when the data directory was located on a slow-to-mount NFS server.
(I have no reason to think that that's exactly what this problem is;
I just cite it to illustrate the kind of thing to be looking for.)
