Not sure what I was thinking here but the space-issue cannot be right though
the "END" does need a semi-colon to be valid pl/pgsql.  Normally after the
semi-colon you would have a newline and then the closing dollar-quotes.
That layout is what I was looking for but mis-translated it into a
white-space error which is obviously wrong since $$somevalue$$ is indeed
valid.
