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. regards, tom lane 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 What I'm looking for is "inverse -b" in an otherwise complete dump.
