FWIW, I like the second one better, and if you check around you'll find
that it matches most other similar stuff, eg
regression=# select 12 like 34;
ERROR: operator does not exist: integer ~~ integer
LINE 1: select 12 like 34;
^
HINT: No operator matches the given name and argument type(s). You might need
to add explicit type casts.
I think the current coding probably is just a typo, but hadn't gotten
around to doing anything about it.
