Strange client encoding issue

["Benjamin Krajmalnik" <kraj(at)illumen(dot)com>]

I am encountering a very strange client encoding issue.

From the logs on the server, I am getting the following:

 

canopy02# tail postgresql-2008-01-16_000000.log
2008-01-16 15:20:03 ESTERROR:  conversion between latin9 and LATIN1 is not supported
2008-01-16 15:20:03 ESTSTATEMENT:  set client_encoding to 'latin9'

2008-01-16 15:20:11 ESTSTATEMENT:  set client_encoding to 'latin9'

The application logging data is using the PostgreSQL ANSI ODBC driver, version 08.01.02.00.

Database server is PostgreSQL 8.2.5 on i386-portbld-freebsd6.2, compiled by GCC cc (GCC) 3.4.6 [FreeBSD] 20060305

 

On page 2 of the datasources tab, in the Connect Settings tab, I have the following:

 

set client_encoding to 'latin1';

 

to force the encoding.

Any ideas on what may be creating this, and how to resolve it?
