I doubt this (code in what language?). Since the column name is
"serializable_value" and there are what looks like Java class names
embedded in the blob ("org.alfresco.service.cmr.version.VersionType",
"java.lang.Enum", ...) these are most likely Java objects in
java serialization format.
The OP should be able to deserialize them with Java. I would expect the
JDBC to return a proper byte array (or maybe a ByteBuffer). That the
field looks different (hex in psql, raw in sqlplus) is most likely
a red herring - that's just for the benefit of humans, but humans can't
read binary data directly.
