INSTALL file nits

I just grabbed a copy of PostgreSQL from

   http://www.apple.com/downloads/macosx/unix_open_source/postgresql.html

and installed it on my Mac OS X (Tiger; 10.4.2) machine.  I followed the
"Short Version" in the INSTALL file until I ran into problems, then did
some workarounds, as discussed below.  Perhaps this file should be made
a bit more explicit or an INSTALL.OSX file could be generated...

./configure
    No reported problems.

gmake
    No such command, but I ran "make --version" and saw that it
    was GNU Make, so I used it.  No reported problems.

su
    This command requires a root password, which does not exist.
         OSX uses "sudo -s" for this sort of thing.

gmake install
    Used make; no reported problems.

adduser postgres
    No such command.  I considered using System Preferences > Accounts
    to add a user, but this seemed like a rather bogus approach, as it
    would put a user in the Login dialog (unlike lp, postfix, ...).  I
    found a (slightly dated) note from Apple, however, that suggested
         just this approach, so I gave it a try.

      http://developer.apple.com/internet/opensource/postgres.html

mkdir /usr/local/pgsql/data
chown postgres /usr/local/pgsql/data
    No reported problems.

su - postgres
    No reported problems (when run under sudo).

/usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 &
/usr/local/pgsql/bin/createdb test
/usr/local/pgsql/bin/psql test
    No reported problems, but the last command left me at a prompt
    with no particular instructions as to what I should do next.
