I thought it might be something like that ... probably plpgsql
transforms "NEW" into something involving a "$" and then the parser
misparses "=$" as a single operator.  I'd argue that it's a plpgsql bug,
if that's right --- if plpgsql is doing text transformations that create
lexical ambiguities, it should be inserting spaces to prevent ambiguity.
