postgresql91-server @9.1.3_0 - umask errors in post-install advice

[bytecrafter@…]

After installing, the on-screen instructions say to do the following:

sudo mkdir -p /opt/local/var/db/postgresql91/defaultdb
sudo chown postgres:postgres /opt/local/var/db/postgresql91/defaultdb
sudo su postgres -c '/opt/local/lib/postgresql91/bin/initdb -D /opt/local/var/db/postgresql91/defaultdb'

However, I use a different umask than the default (I use 077). I had to use the following sequence:

umask 022

sudo mkdir -p /opt/local/var/db/postgresql91/defaultdb
sudo chown postgres:postgres /opt/local/var/db/postgresql91/defaultdb

#because I was somewhere in my home directory when executing the initdb 
#command, it failed with "could not identify current directory: Permission denied".
cd /

sudo su postgres -c '/opt/local/lib/postgresql91/bin/initdb -D /opt/local/var/db/postgresql91/defaultdb'

I realize that my situation is strange enough that the maintainer might prefer to leave the post-install advice simple and straightforward.
