This is completely broken.  The old place was right.

You don't need to quote the argument to 'case'.  Please don't do that, it
makes things less readable.

Can you explain. Do we not want to export PGDATA for other programs we
run from this script?

Well, I guess.  I usually quote all variable mentions.  I saw lots of
VAR=$1 which should be VAR="$1", right?

Correction:  The new place also seems to be okay, but 'export VAR=stuff'
is not portable,  You need to split it into two commands.

Also, you don't need to quote the right side of

FOO=$BAR

Oh, yes you are totally correct.  I am forgetting my old shell stuff.

That is interesting.  I just tried:

    #$ X="1 2"
    #$ Y=$X
    #$ echo $X
    1 2

When do I need quotes around variables then?
