Обсуждение: pgsql: Allow binary-coercible types for cast function arguments and

Allow binary-coercible types for cast function arguments and return types.
Document return type of cast functions.

Also change documentation to prefer the term "binary coercible" in its
present sense instead of the previous term "binary compatible".

Hmm, the error messages you added still use the phrase "binary compatible".
[ click click, grep grep ]  So does psql/describe.c.  The only other
