Subject: [PATCH 6/6] Improve consistency in "object not found" notices in psql

When a \dXXX metacommand failed to find an object, there were some
variability on the response. This aims to make it more consistent by
applying:

* Use psql_error() for all messages regarding objects not being found.
  It's arguably not an error per se, but at least printing all notices
  to the same output channel makes it consistent.
* Formulate the notices in the same way for all objects
* Guard against pattern being NULL
* Never be completely silent unless in QUIET mode, add not found notice
  on the object which lacked it
