While playing with this patch under 8.1.2 at home I discovered a
mistake in how I manually applied one of the hunks to fe-auth.c.
Basically, the base code had changed and so the patch needed to be
modified slightly. This is because the code no longer either has a
freeable pointer under 'name' or has 'name' as NULL.

The attached patch correctly frees the string from pg_krb5_authname
(where it had been strdup'd) if and only if pg_krb5_authname returned
a string (as opposed to falling through and having name be set using
name = pw->name;). Also added a comment to this effect.

Backpatch to 8.1.X.
