Support a --no-tablespaces option in pg_dump/pg_dumpall/pg_restore, so that

dumps can be loaded into databases without the same tablespaces that the
source had.  The option acts by suppressing all "SET default_tablespace"
commands, and also CREATE TABLESPACE commands in pg_dumpall's case.

Gavin Roy, with documentation and minor fixes by me.
