You've had the "for the love of God, upgrade!" note, so let's get to a
possible solution. There are two methods of compressing the database.
One is to erase all old revisions of all old pages. This is quite
destructive, but might work in some cases. The script to do this is
deleteOldRevisions.php and is found in the maintenance directory.

The other, and safer, method, would be to run the compressOld.php
maintenance script, which can be found in maintenance/storage. There
are lots of little switches for customising this, but the defaults
work fine.
