It could be done that way. But given that "$" already has one weird
special case in the operator name rules (ie, it can't be the only
character of an operator name), I feel that we'd be making things overly
complicated.
The proposal back in Aug 2001 was to remove "$" from the set of operator
name characters altogether (which would allow us to use it in
identifiers instead, improving Oracle compatibility). I originally
objected to that idea on backwards-compatibility grounds, but I'm
leaning more and more to the view that it's the right thing to do.
I've re-opened the thread on pgsql-hackers about this, and we'll see
whether any consensus emerges this time.
