Comment (by jarshwah):
I agree, this doesn't need to be a release blocker. The rationale behind
the query not working on postgres is that non-integer constants in a group
by do not actually affect the query at all. It'd arguably be a warning
"are you sure you meant.." but I really don't think this should blow up.
That's a postgres issue though, so not much point debating the merits.
I think documenting the limitation is enough as akaariai suggested. Will a
parameterised constant `Value()` not blow up like the static RawSQL? If
so, then that's the obvious solution to document.
