I've installed the odbc_fdw extension and I've got a DB2 ODBC driver installed.  When I try the instructions at

http://interdbconnect.sourceforge.net/pgsql_fdw/pgsql_fdw-en.html

to create a server object, I don't get any errors reported, and I appear to have successfully created a foreign table, but I don't see either the server or the foreign table in the object browser.

CREATE SERVER remote_db FOREIGN DATA WRAPPER odbc_fdw OPTIONS (dsn 'DB2DSN');

CREATE USER MAPPING FOR postgres SERVER remote_db OPTIONS (username 'jforeman', password 'this-is-a-secret');

CREATE schema remote_query;

CREATE FOREIGN TABLE remote_query.tpids
(tpid int)
SERVER remote_db
OPTIONS (database 'DB2DSN', sql_query 'SELECT TPID FROM DM.V_TPID_DIM.TPID');

All these are apparently fine, although I can't find the foreign table anywhere (it's not visible in the tables in the remote_query schema) on pgAdmin.  The foreign table has a few hundred rows - it's not anything massive that should take a long time to query.

Then I try

SELECT * FROM remote_query.tpids

And the result is

*********Error **********

no connection to the server

Connection reset.

After that, I have no connection to the postgres server, and have to restart the machine before I can reconnect - attempting to use the FDW apparently breaks my existing connection, and prevents me creating any new ones.

2 questions: should I be able to see the foreign table object?  It definitely exists, because if I were to try rerunning the CREATE FOREIGN TABLE command I get an error reporting that it already exists.

Secondly, where should I look to figure out why running the select statement kills the connection, and stops me making any new connection?

Thanks

James
