Turn on mylog debugging

PostgreSQL - 7.1.3 (installed on Linux 2.4.2-2)
PSQLODBC.DLL - 07.01.0007
Visual C++ - 6.0

Can someone tell me how I turn mylog debugging on please.

I am using SQLDriverConnect to connect to the PostgreSQL database.
Here is a snippet of my C connection code:

...

else { // POSTGRESQL
_stprintf((_TCHAR *)in_connect_str,
L"Driver={PostgreSQL};"
L"UID=%s;"
L"PWD=%s;"
L"SERVER=%s;"
L"DATABASE=%s;",
strUID, strPWD, strServer, strDatabase);
}

// *****************
// CONNECT TO SERVER
// *****************
odbc_rc = SQLDriverConnect(hdbc,
(SQLHWND)0,
(SQLTCHAR *)in_connect_str,
(SQLSMALLINT)in_connect_str_len,
(SQLTCHAR *)out_connect_str,
(SQLSMALLINT)out_connect_str_len,
&stringlen,
SQL_DRIVER_NOPROMPT);

...

Thanks for any help on this.

Andy.
