I've managed to work around this by adding a config line like:

gsql-supermaster-query=select account from supermasters where ip='%s'

In this setup, only IP addresses need to be listed in the supermasters
table and the other checks are bypassed.

This might need some careful checks if the database schema / the
expected returned field list etc changes at some point in the future.
