Sorry I didn't give more detail. OS is Linux 2.2 kernel, PostgreSQL is
6.5.3. The problem is that I copied the .../base/* directories elsewhere in
preparation for making base a symlink to a different filesystem with more
space. I then screwed up and removed everything in /var/lib/pgsql, not just
the base directories. This necessitated a reinstall of PostgreSQL.
I know, I know ... it was a very stupid maneuver on my part, but it's a
strange feeling to know that I've GOT the database files, I just can't use
'em. Yet.
Thanks, and
Cheers!

If the two PostgreSQL installations are the same major version, then you
copy the entire /var/lib/pgsql tree over. Not just the base/* trees.
What version, what OS?
