​I don't understand how placing a non-canonical host name in the
pg_hba.conf can ever result in the following condition being true:

"If a host name is specified [...] that name is compared with the result of
a reverse name resolution of the client's IP address (e.g., reverse DNS
lookup, if DNS is used)."
