When is 6.6 being released? I'm not sure about the greedy lexer, I don't
really know enough to comment, but at first glance, yes fine. The question
is, though, what are possible operators. Do we limit the user-defined
operators in PG to only to a specific subset of characters. Perhaps we
should lex each operator separately, and then get the compiler to construct
logical operators from the physical components that it gets.
