I think actually what he needs is what Peter suggested upthread, namely
to weaken the context-restriction on the int-to-bool cast. For a
comparison like
WHERE boolcol = 1
the system is still gonna see that as a bool vs int comparison, and it
won't take it unless int-to-bool is an implicit cast.
Another route might be to create a bool = int operator. That seems less
likely to break expected behaviors, but it'd be more work.
