No, applications dont do lookups theirself.
The os (or rather the resolver lib) decides
how it works and therefore both 7.2 and 8.0
will behave the same.
I think you have different user policies in their
pg_hba.conf and 8.0 might (per default) want to
check ident. And if you firewall it or so it might
take a while to timeout.
