I don't know about all the aspects regarding Postgresql, but you could
create another partition, either from current free space, or by adding
another drive and migrate /usr/local to it.

Create the new space (format existing unused space, add a new drive)
mount the new space (/tmpmnt or something)
Boot to single user, insure your postgresql database is not active.
Copy /usr/local to /tmpmnt
Modify /etc/fstab to mount /usr/local on /tmpmnt

Once you verify this all works, you will need to reboot to single user,
unmount your new /usr/local so you can remove the old stuff that was in
the old /usr/local partition/directory in order to recover that space.

Others may shoot this down because of issues with Postgresql I'm not
aware of, but I do this all the time to move stuff around or create new
space.
