Make DROP IF EXISTS more consistently not fail

Browse Source 
Some cases were still reporting errors and aborting, instead of a NOTICE
that the object was being skipped.  This makes it more difficult to
cleanly handle pg_dump --clean, so change that to instead skip missing
objects properly.

Per bug #7873 reported by Dave Rolsky; apparently this affects a large
number of users.

Authors: Pavel Stehule and Dean Rasheed.  Some tweaks by Álvaro Herrera
