After removing an orphaned postmaster.pid the above seemed to have started

Thinking postmaster is running I tried this:
$ psql crm
Password:
FATAL: password authentication failed for user "rshepard"
DETAIL: User "rshepard" has no password assigned.
Connection matched pg_hba.conf line 80: "local all all
md5"
psql: FATAL: password authentication failed for user "rshepard"
The crm database is owned by me.

From man initdb:
-W, --pwprompt
Makes initdb prompt for a password to give the database superuser.
If you don't plan on using password authentication, this is not
important. Otherwise you won't be able to use password
authentication until you have a password set up.
The superuser already exists in /etc/passwd.

Yes. It's the same password I use for logging in as a user. If it's the
superuser password being requested, then that's the same as my user
password.
The Slackware rc.postgresql file for 9.5 has changed from 9.3 and earlier.
It's asking for passwords:
if [ ! -e $DATADIR/PG_VERSION ]; then
echo "You should initialize the PostgreSQL database
at location $DATADIR"
echo "e.g. su postgres -c \"initdb -D $DATADIR
--locale=en_US.UTF-8 -A md5 -W\""
exit 6
fi
Note the '-W' at the end. But, I ran initdb from the command line as user
postgres.
