Not that I know of. It's simple enough to do from the application side
of things of course (well, in most languages) but there's no general
file access.
You can do various tricks to grab text values (see psql in the docs "SQL
Interpolation") but you'd need to escape the values. Not sure that's any
cleaner than the large-object approach.
