I thing so ex-MySQL needs exact DESCRIBE, exact SHOW statement. It is
some, what they used long time and then they missing it.
Hypothetically we could have a "super hook" on server side - or hook
on psql and we can implement these statements in some contrib module.
Personally I don't thing, so this can have any strong effect. If these
modules are not default, then ex-MySQL will have a problem. And if
ex-MySQL people will be happy with SHOW support, then they will be
dissatisfied for PostgreSQL user's rights.

p.s. super hook should be useful not only for mysql's statement
