PostgreSQL provides two distinct ways to store binary data: Binary data can be stored in a table using the data type bytea . By using the Large Object feature which stores the binary data in a separate table in a special format and refers to that table by storing a value of type oid in your table. Different methods are used to access the BLOBs depending on which storage type you choose: To use the bytea data type you should use the getBytes() , setBytes() , getBinaryStream() , or setBinaryStream() methods. To use the Large Object functionality you can use either the LargeObject class provided by the PostgreSQL JDBC driver, or by using the getBLOB() and setBLOB() methods. Using setBinaryStream on an OID column yields...
