Whether or not max relations is the root of the login hang problem,
you likely have gotten a fair bit of bloat in your database if your
setting was too low by a factor of 10 for so long. You may need to
look at recovering lost space in bloated tables and / or indexes. If
the bloat is real bad, look at dumping / restoring the database for a
fresh start. It's a pain because it requires downtime, but it's often
faster than anything else for a badly bloated database.
