I'm not getting quite that behavior --- how did you invoke it exactly?

But I agree that the error message is broken in the IPv6 code. On a
machine with no IPv6 support (HPUX 10.20), I still get the right thing
from CVS tip:

$ createdb -p 7777
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.7777"?
createdb: database creation failed
$

But with the IPv6 code compiled (Red Hat 8.0), the error message is the
wrong one (it's for TCP not Unix connections):

$ createdb -p 7777
psql: could not connect to server: No such file or directory
Is the server running on host ??? and accepting
TCP/IP connections on port 7777?
createdb: database creation failed
$

I noticed this some weeks ago, but had not got round to investigating yet.
