Been doing it that way since 6.3 (before pg_restore existed iirc). I
keep doing it that way because there are no real space issues for me,
and if I ever need to restore a system from backup, I can upgrade at the
same time and still be able to massage the dump file into the new
version of PostgreSQL if required. I think the easy answer is to just
assume the file is a text dump if a signature cannot be found, and just
pipe it to psql (so we don't have to worry about handling \connect or
\copy ourselves).

And some advantages.

I always assume the worst (as one should with backups IMO) - that
something will go wrong and I may need to massage the data for some
reason.
The bottom line is, whatever view you take, plain text backups can be
done and are done - thus we should try to support them.
