A look at the pg_dump source code says that it skips blobs if any of
-s, -n, -t are used. There's a -b switch to undo that and include
them anyway, but no "inverse -b" to skip them in an otherwise-complete
dump.
So you could do something along the lines of pg_dump -t '*' ...
although this will result in *all* non-schema-named objects being
excluded, I believe, which might be a problem.
