See https://www.postgresql.org/docs/11/datatype-oid.html, OID data type is not necessarily referring to large object, therefore it's totally OK, if there is no LargeObject mapped to the numerical value, e.g. 'table'::regclass.
Currently PostgreSQLOidDataType would fail with smth. like org.dbunit.dataset.DataSetException: org.postgresql.util.PSQLException: ERROR: large object 16548 does not exist

Thanks for the report. Please create a merge request with a proposed fix and a test that shows the problem so it stays fixed.

Confirmed still open.
PostgreSQLOidDataType#getSqlValuehas a commented-out attempt at swallowing this case, with an explicit note that doing so unconditionally would hide real errors — so this needs a real fix that distinguishes "not a large object" from other SQL failures (e.g. by inspecting the driver's SQLState) rather than a blanket catch. Leaving open.
