| UnrecognizedTypeHandler | Handles "conversions" for columns sent by the database with unknown OIDs. This differs from TextHandler in that its a text-only handler (we don't want to receive binary representations of the types registered here). Note that this handler is also used in the very initial query that loads the OID mappings (chicken and egg problem). |
