Thread: pgsql: Doc: improve examples for json_populate_record() and related fun

Doc: improve examples for json_populate_record() and related functions.

Make these examples self-contained by providing declarations of the
user-defined row types they rely on.  There wasn't room to do this
in the old doc format, but now there is, and I think it makes the
examples a good bit less confusing.
