postgreSQL install via MacPorts on OSX
In order to install PostgreSQL on OSX, you need to know which versions are currently supported.
Use this command to see what versions you have available.
sudo port list | grep "^postgresql[[:digit:]]\{2\}[[:space:]]"You should get a list that looks something like the following:
postgresql80 @8.0.26 databases/postgresql80
postgresql81 @8.1.23 databases/postgresql81
postgresql82 @8.2.23 databases/postgresql82
postgresql83 @8.3.23 databases/postgresql83
postgresql84 @8.4.22 databases/postgresql84
postgresql90 @9.0.23 databases/postgresql90
postgresql91 @9.1.22 databases/postgresql91
postgresql92 @9.2.17 databases/postgresql92
postgresql93 @9.3.13 databases/postgresql93
postgresql94 @9.4.8 databases/postgresql94
postgresql95 @9.5.3 databases/postgresql95
postgresql96 @9.6beta2 databases/postgresql96
In this example, the most recent version of PostgreSQL that is supported in 9.6, so we will install that.
sudo port install postgresql96-server postgresql96You will see an installation log like this:

To create a database instance, after install do
sudo mkdir -p /opt/local/var/db/postgresql96/defaultdb
sudo chown postgres:postgres /opt/local/var/db/postgresql96/defaultdb
sudo su postgres -c '/opt/local/lib/postgresql96/bin/initdb -D
/opt/local/var/db/postgresql96/defaultdb'

---> No broken files found.The log provides instructions on the rest of the steps for installation, so we do that next.
sudo mkdir -p /opt/local/var/db/postgresql96/defaultdb
sudo chown postgres:postgres /opt/local/var/db/postgresql96/defaultdb
sudo su postgres -c '/opt/local/lib/postgresql96/bin/initdb -D
/opt/local/var/db/postgresql96/defaultdb'Now we start the server:
sudo port load -w postgresql96-serverVerify that we can connect to the server:
su postgres -c psqlYou will see a prompt from postgres:
psql (9.6.1)
Type "help" for help.
postgres=#Here you can type a query to see that the server is running.
postgres=#SELECT setting FROM pg_settings WHERE name='data_directory';And see the response:
setting
------------------------------------------
/opt/local/var/db/postgresql96/defaultdb
(1 row)
postgres=#Type \q to quit:
postgres=#\qAnd you will be back at your shell prompt.
Congratulations! You now have a running PostgreSQL instance on OS/X.
