FWIW, I agree with David on this point. I find it bizarre and unhelpful
that slashUsage shows \dt, \di, etc as separate commands and fails to
indicate that they can be combined. We could merge these entries into
fprintf(output, _(" \\d[tivmsE][S+] [PATRN] list relations of specified type(s)\n"));
which would both remind people that they can give more than one type,
and shorten the already-overly-long list.

That seems quite irrelevant to this proposal.
