BLOB handling compatibility with PostgreSQL > 7.4

Dear experts,

We would like to upgrade the Postgres version from our current 7.3 but
have problems with handling BLOBs via ODBC.
We use unixODBC-2.2.11 and psqlodbc-08.01.0101.
With postgres 7.3 lo type was mapped to SQL_C_BINARY and that's changed
since postgres 7.4.
Is it an ODBC or a driver issue? Are there any plans to fix the problem?

Thank you,
Irina
