Обсуждение: pgsql: Rework echo_hidden for \sf and \ef from commit e4d2817.

Rework echo_hidden for \sf and \ef from commit e4d2817.

PSQLexec's error reporting turns out to be too verbose for this case, so
revert to using PQexec instead with minimal error reporting. Prior to
calling PQexec, we call a function that mimics just the echo_hidden
piece of PSQLexec.
