Following up from a suggestion from Tom Lane[1] to improve the documentation of
boolean predicate JSON path expressions, please find enclosed a draft patch to

I'm starting to think of it as a project. Here's a quick project statement.
The purpose is to generate improved Doxygen output while making maximal use of
how Postgres currently does program comments.
