error in PgResultSet#getBlob(int)

It seems org.postgresql.jdbc.PgResultSet#getBlob(int) is wrong in version group: 'org.postgresql', name: 'postgresql', version: '42.1.1' IDE shows me its code as:

  public Blob getBlob(int i) throws SQLException {
    checkResultSet(i);
    if (wasNullFlag) {
      return null;
    }

    return makeBlob(getLong(i));
  }

and I think there should not be makeBlob(getLong(i)); but makeBlob(getColumnOID(i)); cause makeBlob wants oid as only param, and getLong seems to return Long value of that column and not an oid I’m getting an error here:

Exception in thread "main" org.postgresql.util.PSQLException: Bad value for type long : \xabcd
	at org.postgresql.jdbc.PgResultSet.toLong(PgResultSet.java:2860)
	at org.postgresql.jdbc.PgResultSet.getLong(PgResultSet.java:2114)

Searching Google with: “jdbc getblob postgresql” gets you to previous discussions on this question. In short, blob/clob points to PostgreSQL’s “Large Object” system. bytea and text types are accessed via getBytes and getString respectively.
