----------------------+---------------------------------
 After installing the port, a life-saver note is printed providing setup
 instructions

 {{{
 notes "\nTo create a database instance, after install do\n\
         sudo mkdir -p ${dbdir}\n\
         sudo chown ${dbuser}:${dbgrp} ${dbdir}\n\
         sudo su ${dbuser} -c \'cd ${dbhome} && ${libdir}/bin/initdb -D
 ${dbdir}\' "
 }}}

 Unless I'm misreading things or my machine is in a really weird state (as
 these failed) there's an issue with it though: on the last line, it cds to
 `${dbhome}` as `${dbuser}`, but `${dbhome}` *is still owned by root*

 * `${dbdir}` is `${dbhome}/defaultdb`
 * both directories are created as root
 * chown is only applied to `${dbdir}`

 so the postgres user doesn't have access to `${dbhome}` to which it tries
 to cd.

 I don't really know whether the proper fix is to just not cd there at all
 (is it really necessary for initdb?) or to `chown -R ${dbdir}` instead of
 just `${dbhome}`.

 Assuming it's not an error between my keyboard and chair, I think it's a
 long-standing issue too, I remember hitting it on previous versions but
 assuming I'd screwed up somewhere.
