OK. Here's another (additional) patch. This gets the PostgreSQL version upon
connection, and then uses it to determine what to return from SQLGetInfo for
SQL_DBMS_VER, SQL_MAX_ROW_SIZE, SQL_MAX_STATEMENT_LEN, SQL_OJ_CAPABILITIES
and SQL_OUTER_JOINS. This makes all my changes backward compatible. It also
increments the revision number to 07.01.0001 and corrects the format of the
version number which I previously mistyped as 7.1.0000 (as per ODBC
requirements).

NB: I've not tested this under *nix, only W2K.

Regards, Dave.
