Yeah, I was testing it with some longer geometries and it was a great
help. My main concern is that it is not too clear that the error location
is at the *end* of the quoted string - hence the arrow. And it seems
useful to put a position number in case all of the string doesn't fit in
the quoted context. Paul, this is probably something you'd be good at -
any better ideas?

Of course :)  If we switch the elog()s over to ereport() then we can add
additional HINTs for whichever messages we like.


ATB,
