I believe I did.
I issued:
  $ sudo port install postgresql90-server
and it told me:
  --->  Installing postgresql90-server @9.0.4_0

  To create a database instance, after install do
   sudo mkdir -p /opt/local/var/db/postgresql90/defaultdb
   sudo chown postgres:postgres /opt/local/var/db/postgresql90/defaultdb
   sudo su postgres -c '/opt/local/lib/postgresql90/bin/initdb -D /opt/local/var/db/postgresql90/defaultdb'

  To tweak your DBMS, consider increasing kern.sysv.shmmax by adding an increased kern.sysv.shmmax .. to /etc/sysctl.conf
  --->  Activating postgresql90-server @9.0.4_0
  --->  Cleaning postgresql90-server

Can you tel me why you think I didn't install it?

Thank you.

Reading through this thread it is not clear that Tena installed the postgresql90-server.
$ sudo port install postgresql90-server
