Update:

To be clear, the main reasons I put the man page table in a different database was to make the main database smaller (75%) smaller; and so the daily backups are faster and use less resources. These backups take up less disk space on both the main server and the backup server.

From a DB CPU perspective, there is little to no performance difference having one huge database or two smaller ones.
