Sorry for the noise.

Indeed I use a third-party GUI and it seems that it is wanting to handle the
"?" as an input parameter placeholder as opposed to an operator.  I just lit
up psql and confirmed that test query executed as expected.

I get a "syntax error at or near $1" when I try to send a similar query
through the JDBC driver (as part of a create table column check constraint).

Given that direct function calls are available for all of the question-mark
containing operators I'll likely just stick to those for now.  I'm unsure
whether this a fundamental issue with JDBC and related escaping (or the
equivalent for the commercial GUI that I use) or if a solution is possible
(I would assume yes given psql seems to know how to deal with it) but having
now realized the situation I'll be able to course-correct in the future.

Thanks for the quick response!
