ODBC error - Mailing list pgsql-general

I'm trying to isolate a problem - using Cold Fusion, and sending to pg
a large text block, I'm getting an error:

ODBC Error Code = 08S01 (Communication link failure)

Error while executing the query; Query string is too long

Is this a Cold Fusion problem, or a postgresODBC driver problem? I
know that pg now has no limit on text objects.

Using pg 7.1, on Debian stable, using CF 4.5

Thanks.
