Use E'' strings internally only when standard_conforming_strings =
'off'. This allows pg_dump output with standard_conforming_strings = 'on' to generate proper strings that can be loaded into other databases without the backslash doubling we typically do. I have added the dumping of the standard_conforming_strings value to pg_dump. I also added standard backslash handling for plpgsql.
