gssencmode=disable in your connection options; but that's a tad
inconvenient probably.

Ugh, not only Heimdal but a very obsolete version thereof? It borders
on negligence for the homebrew PG package to be building against that.
They should be pulling in homebrew's MIT Kerberos package and using
that, if they want to enable GSSAPI.
