No, I think it's just plain broken. There are two bugs there, not just
one, as can be seen by comparison of this processSQLNamePattern call to
every other one that's dealing with schema-qualifiable names. It should
be more like
processSQLNamePattern(pset.db, &buf, pattern, false, false,
"n.nspname", "c.relname", NULL,
"pg_catalog.pg_table_is_visible(c.oid)");
As-is, it's passing nspname for "namevar" and relname for "altnamevar".
That sort of manages to not fail for unqualified names, but even there,
I fail to see how matching to schema names is anything but a bug.
This code came in with some other \d commands for other FDW-related
objects that do not have schema-qualified names, so I guess that it
was just mis-copied-and-pasted from one of those.
