After fixing `IllegalArgumentException: Cannot find PostgreSQL type 'POSTGRESQL_TYPE_UNSPECIFIED' in column type when process binary protocol value`, there's new exception thrown: ``` Exception in thread "main" org.postgresql.util.PSQLException: ERROR: column "create_time" is of type timestamp without time zone but expression is of type bytea ``` From PostgreSQL driver source, Date/Time/Timestamp/Distinct/Other will use Oid.UNSPECIFIED, all of them set parameter as string, so read unsepcified parameter as string. but still exception: ``` Exception in thread "main" org.postgresql.util.PSQLException: ERROR: column "create_time" is of type timestamp without time zone but expression is of type character varying ``` Since `BackendConnection` use `PreparedStatement.setObject(int parameterIndex, Object x)`, Oid is changed as ``x`'s` Java object type, e.g. String. In order to keep Oid.UNSPECIFIED, a new type `TypeUnspecifiedSQLParameter` added. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
