Natural solution to this seems to move most of pg_dump functionality
into backend as functions, so we have pg_dump_xxx() for everything
we want to dump plus a topological sort function for getting the
objects in right order.
The main things left into pg_dump the library would be support various ways
to format the dump results into text, tar and "dump" files.
