PostgreSQL Server Setup on Mac OS with MacPorts

This is in particular aimed at using multiple versions of PostgreSQL at different ports.

export VERSION=15

Install

port info postgresql${VERSION}-server
port install postgresql${VERSION}-server

Initial Setup

sudo mkdir -p /opt/local/var/db/postgresql${VERSION}/defaultdb
sudo chown postgres:postgres /opt/local/var/db/postgresql${VERSION}/defaultdb
sudo su postgres -c 'cd /opt/local/var/db/postgresql${VERSION} && /opt/local/lib/postgresql15/bin/initdb -D /opt/local/var/db/postgresql15/defaultdb'

change the port in /opt/local/var/db/postgresql${VERSION}/defaultdb/postgresql.conf

our|my convention is to use "54${VERSION}", currently 5415

Starting manually / Troubleshooting

as user postgres, e.g. sudo -i -u postgres

/opt/local/lib/postgresql${VERSION}/bin/pg_ctl -D /opt/local/var/db/postgresql${VERSION}/defaultdb start -l /opt/local/var/log/postgresql${VERSION}/postgres.log

Add User

initially also as user postgres

CREATE USER tom WITH SUPERUSER LOGIN PASSWORD 'tom';
CREATE DATABASE tom owner tom
