Fix up pg_dump to do string escaping fully correctly for client encoding
and standard_conforming_strings; likewise for the other client programs that need it. As per previous discussion, a pg_dump dump now conforms to the standard_conforming_strings setting of the source database. We don't use E'' syntax in the dump, thereby improving portability of the SQL. I added a SET escape_strings_warning = off command to keep the dumps from getting a lot of back-chatter from that.
