upgrade problem

Hi,
Darn, I thought I had this under control.
I just installed 8.3.0 and it seemed to go OK.

The server seems to be running OK:
> $ sudo -u postgres pg_ctl restart
> pg_ctl: PID file "/usr/local/pgsql/data/postmaster.pid" does not exist
> Is server running?
> starting server anyway
> pg_ctl: could not read file "/usr/local/pgsql/data/postmaster.opts"

But now, trying to create a database I get an error:

> $ createdb testdb
> createdb: could not connect to database postgres: 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"?

Here's my $PGDATA:
> $ sudo -u postgres ls -al $PGDATA
> total 32
> drwx------ 14 postgres wheel 476 Feb 28 17:21 .
> drwxr-xr-x 9 root wheel 306 Feb 28 17:19 ..

> drwx------ 4 postgres wheel 136 Feb 28 17:21 pg_xlog
> -rw------- 1 postgres wheel 16552 Feb 28 17:21 postgresql.conf

And here's my config:
> BINDIR = /usr/local/pgsql/bin
> DOCDIR = /usr/local/pgsql/doc
> INCLUDEDIR = /usr/local/pgsql/include
> PKGINCLUDEDIR = /usr/local/pgsql/include

> SHAREDIR = /usr/local/pgsql/share
> SYSCONFDIR = /usr/local/pgsql/etc
> PGXS = /usr/local/pgsql/lib/pgxs/src/makefiles/pgxs.mk
> CONFIGURE = '--with-includes=/sw/include:/opt/local/include' '--

Hopefully, it is something simple. Help, please.
