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.

Hm:
pg_dump -v -t '*' > andreak-noblob.dmp
pg_dump: reading extensions
pg_dump: identifying extension members
pg_dump: reading schemas
pg_dump: reading user-defined tables
pg_dump: [archiver (db)] query failed: ERROR: permission denied for relation pg_authid
pg_dump: [archiver (db)] query was: LOCK TABLE pg_catalog.pg_authid IN ACCESS SHARE MODE
pg_dump: reading extensions

What I'm looking for is "inverse -b" in an otherwise complete dump. Any plans to add that?
