bug in postodbc

I woud like ot report a bug in Postgresql ODBC driver. I use postgresql
ver 6.3 and ODBC driver version 6.30.0250 and MS ACCESS 97. When I try
to insert backslash \ into a varchar field in linked table through MS
ACCESS it doesn't work. Error messages :

ODBC-insert on a linked table 'test' failed.

Error while executing the query;
ERROR: parser: parse error at or near "" (#1)

And a piece of psqlodbc.log

conn=37558536, query='BEGIN'
conn=37558536, query='INSERT INTO "test" ("a") VALUES ('\')'
ERROR from backend during send_query: 'ERROR: parser: parse error at or

Is this really a bug?
