Indeed. I don't quite see a reason not to remove this duplication,
and both routines in pg_restore.c and the pg_dump code are the same.

dumputils.h is only used by pg_dump and pg_dumpall, and its top
comment documents exactly that, so using this location for a routine
that would be used by a pg_restore path is a bit strange to me for
something that is qualified as a "dump" routine in your patch.

Perhaps we should just use a more centralized place, like file_utils.c
so as all frontends could benefit of it?

Please make sure to add it to the next commit fest that will begin in
July, this refactoring proposal is too late to be considered for v18.
