Okay, I'm sitting on the fence on this one ... but, as DBA for several
PgSQL installs on at least a half dozen machines or more, if someone
restarts PG with the wrong -D pointer, they haven't setup their machine to
live through a reboot ... first thing any DBA *should* be doing after they
have 'initdb'd their system is add the appropriate start-up scripts for
after the reboot ...

Also, what is the difference between forgetting where you put it in an
initdb or on the first postmaster? Why not put in a 'safety'? If you
start up postmaster with -D on a directory that doesn't yet exist, it
prompts the DBA as to whether they are certain that they wish to do this?

Just thoughts ... I'm happy enough with initdb *shrug*
