I haven't finished reviewing this yet - but there are some things that
need to be fixed.
First, either the creation of the destination directory needs to be
delayed until all the sanity checks have passed and we're sure we're
actually going to write something there, or it needs to be removed i

If you use ALTER ROLE/DATABASE SET to configure an invalid
search_path, PostgreSQL 9.1 issues a complaint about the invalid
setting on each new connection. This is a behavior change relatively
to previous releases, which did not. git bisect blames this commit:
