Nice. I think this is very useful.

I spotted one issue, which can be seen by compiling with --enable-nls
and --enable-cassert. In that case \dC+ fails with an assertion error:

\dC+ json
psql: print.c:3564: printQuery: Assertion `opt->translate_columns ==
((void *)0) || opt->n_translate_columns >= cont.ncolumns' failed.
Aborted (core dumped)

This is because translate_columns[] in listCasts() needs to be updated.

Similarly, in describeFunctions(), translate_columns_pre_96[] needs to
be updated to support connecting to pre-9.6 servers.

The translate_columns entries for this new column should be true, so
that the "yes"/"no" gets appropriately translated. That means that
describeOperators() will need a similar translate_columns array.
