Good guess ... what actually happenend was that after a couple of these
getaddrinfo() SIGSEGV's on AIX, one of our Slony-replica was out of
sync. Long story short, it all didn't make sense.
Now the scary thing is that not only did this crash rollback a committed
transaction. Another session had enough time in between to receive a
NOTIFY and select the data that got rolled back later.
