Bug reference:      2266
Logged by:          Gerhard Lutz
Email address:      gerhard(dot)lutz(at)mbtech-group(dot)com
PostgreSQL version: 8.1.3
Operating system:   Windows XP SP2
Description:        SQL_ATTR_CONNECTION_DEAD always returns SQL_CD_TRUE
Details: 

I want to upgrade my PostgreSQL server from 8.0.4 to 8.1.3.
My C++ application connects to the database via ODBC (ODBC driver:
PostgreSQL Unicode).

In 8.0.4 I was able to check after an error if the database connection get
lost.

::SQLGetConnectAttr(g_hDBConnection, SQL_ATTR_CONNECTION_DEAD,
&uConnectionDead, 0, &nLen);

returned SQL_CD_TRUE or SQL_CD_FALSE.

In 8.1.3 this function always returns SQL_CD_TRUE, even when the database
connection is still available. Has this to do with ODBC 3.5 or is it a bug
in the ODBC driver?
