I get this error when trying to set up a .net application using the ODBC
driver in Linux/Mono.  The same application works ok in odbc under
Windows/IIS, although I'm not sure that the ODBC drivers are the same.
Google seemed to only bring up some outdated links like
http://developer.postgresql.org/cvsweb.cgi/pgsql-server/src/interfaces/odbc/Attic/convert.c?rev=1.4

Anyone seen this one before? Anyone have a pointer on what might be
wrong? TIA

PS. I am aware of npgsql, but need this to run initially on odbc for a
proof of concept.
