How about also storing the encoding of the path/filename as well? This
would allow the restore to do the right thing for display purposes and
also when going to a system that uses a different encoding. Obviously
you wouldn't know this for Unix derivatives, but for most other systems
this would seem to help.

As others have said; BYTEA is probably the best datatype for you to
use. The encoding of BYTEA literals is a bit of a fiddle and may need
some changes, but it's going to be much more faithful to your needs of
treating the filename as an opaque blob of data.
