The syntax for specifying "BLOB literals" is a bit different in Postgres. You need to encode the bytes as octal values not hex values.

See: http://www.postgresql.org/docs/8.2/static/datatype-binary.html

INSERT INTO "FUND_ASSET_DTO_BINARY"
("fundAssetDTOBinaryID', OBJ_VERSION, "binaryFundAssetDTO")
VALUES
(1, 0, \254\355\00 ... )

Btw: are you sure you want to use case-sensitive table and column names? This usually causes more trouble than it's worth. But that's just my opinion.
