In order to install this package, you must *first* create a user/group called
pgsql, which PostgreSQL will run as.  Locally, I've used the following commands:

> groupadd pgsql
> useradd -d /usr/local/pgsql -m -c "PostgreSQL Admin" -g pgsql pgsql

After that is created, uncompress the package using 'gunzip <pkgname>' and then
install using 'pkgadd -d <pkgname>' ...

Once installed, su to the new user you created above to perform the initialization
procedures, as follows (please note this assumes you are using [t]csh, not [ba]sh):

> set path = ( $path /usr/local/pgsql/bin )
> initdb --pglib=/usr/local/pgsql/lib --pgdata=/usr/local/pgsql/data

At this point, you should be ready to start up the daemon itself, and begin work.
On my machines, I use a simple script, as follows:

#!/bin/tcsh
setenv HOMEDIR /usr/local/pgsql
${HOMEDIR}/bin/postmaster -o "-F -o ${HOMEDIR}/errout -S 16384" \
        -i -p 5432 -D${HOMEDIR}/data &
