------------------------------------------------------------
In addition, I am not seeing the parser support "RLIKE", you might also need to
touch Parser.jj to add "RLIKE" in parser.
Regarding to the runtime code, I think CALCITE-3063 tried to support
postgresql's POXIS_REGEXP, which is be similar or same to MySQL's RLIKE, as
both postgresql and MYSQL state their POXIS_REGEXP/RLIKE support regular
expressions similar to those used by Unix utilities such as grep and sed. So
you might can reuse existing code for execution, if that's possible.
