Using a recent pg_restore (tested with 9.1.2, verbose mode on) and a custom-format dump containing large objects, you should see messages like this: pg_restore: creating TABLE image pg_restore: executing BLOB 126810 pg_restore: executing BLOB 133157 ... pg_restore: restoring data for table "image" pg_restore: restoring BLOBS pg_restore: restored 1111 large objects ... pg_restore: setting owner and privileges for BLOB 126810 pg_restore: setting owner and privileges for BLOB 133157 ... If you're not seeing those messages, maybe your dump didn't actually include large objects (e.g. because you didn't dump the whole database and left off --blobs). It looks like you are correct that the blobs are restored inside a single transaction, even without the --single-transaction flag.
