Agreed.

As this is for a new major PG release, I'd be in support of that.  I
would like to get the kerberos tests working on a FreeBSD buildfarm
animal with MIT Kerberos installed, if possible.

Agreed.  Still, I wouldn't go and break it for minor releases, but for a
new major version saying we no longer support Heimdal seems reasonable.
Then folks have the usual 5-ish years (if they want to delay as long as
possible) to move to MIT Kerberos.

I'd be happy with that and can add the appropriate documentation noting
that we require MIT Kerberos.  Presumably the appropriate step at this
point would be to check with the RMT?

Thanks!
