Yes it does:

could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/
postgresql/.s.PGSQL.5432"?

Do you know where can I find that in the source code? I used the
8.3.3 source from postgresql.org. I did use apt-get to install the
source, but I had trouble with the dev headers when I did that. I
noticed some bin files in /usr/local/pgsql/bin hung around after
doing apt-get remove, but I'm pretty sure the install that is being
used is from the build/install of the 8.3.3 source.
