I decided to give this a go after all :-) The attached patch does the

following but it does *not* check whether the user is connected to
PostgreSQL 7.0.x or 7.1 first (as would be required for some of the
features) - the driver doesn't do this at all afaik and it's beyond my
capabilities to implement such checking in code that doesn't look like it
was written by my 1 year old daughter!

1) The driver now reports no maximum query length (SQL_MAX_QUERY_SIZE).
2) The driver now reports no maximum row length (SQL_MAX_ROW_SIZE).
3) The driver now reports that Outer Joins are supported (SQL_OUTER_JOINS),
but still does not report oj capabilities (SQL_OJ_CAPABILITIES).
4) The version number has been incremented to 7.1.0000 in psqlodbc.h *and*
psqlodbc.rc

Dave Page
