Tom,
we discussed this problem some months ago when I started using 7.4 on 
SuSE 8.1. Since 7.4 accepts IPV6, the kernel will always deliver IPV6 
addresses, that's why I find most IPV6 problems. While this behaviour 
might be irritating, it shouldn't be much of a problem if known.

How about silently creating a IPV6 style host internally for every IPV4 
pg_hba.conf entry? It won't make any sense to handle a real IPV4 address 
different from an IPV4 address converted to IPV6 address space.
