I'm using only IP addresses in pg_hba.conf.

There was nothing in the postmaster log indicating a problem.

The only thing I saw strange was multiple postmasters spawning and
disappearing.

The errors I got in the JDBC drivers was the connection pool timing out
trying to get a connection, so it's possible they were working, just
taking horribly long to connect. Timeouts for Nagios monitoring PG was
10 seconds; pools were 20 seconds. In three years, I've probably seen 3
time outs. :)
