Most pg_dump.c global variables, which were passed down individually to dumping routines, are now grouped as members of the new DumpOptions struct, which is used as a local variable and passed down into routines that need it. This helps future development efforts; in particular it is said to enable a mode in which a parallel pg_dump run can output multiple streams, and have them restored in parallel. Also take the opportunity to clean up the pg_dump header files somewhat, to avoid circularity. Author: Joachim Wieland, revised by Álvaro Herrera Reviewed by Peter Eisentraut
