======================================================================

To initialize the database, you should run initdb as the "pgsql" user
(if you want to use your locale for collation, edit ~pgsql/.profile
and set the locale to your preference first).

Example:

  su -l pgsql -c initdb

You can then start PostgreSQL by running:

  /usr/local/etc/rc.d/010.pgsql.sh start

For postmaster settings, see ~pgsql/data/postgresql.conf
For more tips, read ~pgsql/post-install-notes
