psql -p 5433; create database test; \c test failing

Hi,

this is from HEAD of a few days ago, it looks suspicious to me.
8.2devel runs on port 5433.

markus(at)katerina2:~/pgsql$ bin/psql -p 5433 template1 markus
Welcome to psql 8.2devel, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit

template1=# create database test;
CREATE DATABASE
template1=# \c test
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.5432"?
Previous connection kept

Why is it trying to use 5432? Am I missing something? Is that the
expected behaviour?

Michael Fuhr hinted that
http://archives.postgresql.org/pgsql-committers/2006-02/msg00139.php
may be the cause of that.
