Thanks, Tom. That does clear up what I've seen over the years. The
executables go in /usr/bin/ (at least they do with Slackware), but $PGDATA
is what I've seen changed between building from source and installing
packages.

I see in postgresql.SlackBuild where the data directories are specified.
I'll change that from /var/lib/pgsql/data to /usr/local/pgsql/data and
rebuild the package.

Very much appreciated,
