Doesn’t seem worth the effort. The documentation is the best discovery
resource while whatever admin tool one uses, psql in core, provides info
about schema columns. pg_typeof is documented but seldom useful. Maybe a
cross-reference to it is warranted elsewhere but adding a complete
sub-section for this topic seems a bit much.
If one were to submit such a patch I’d consider it but its not something
that I consider as a existing omission.
