odbc1.diff changes the text on the Protocol Radio buttons on the driver
dialogue from '6.4/6.5' to '6.5+' and removes some C++ comments from resource.h (which VC++ insists on putting there). odbc2.diff adds code to query the PostgreSQL version upon connection. This is then used to determine what values to return for from SQLGetInfo for SQL_DBMS_VER, SQL_MAX_ROW_SIZE, SQL_MAX_STATEMENT_LEN, SQL_OJ_CAPABILITIES and SQL_OUTER_JOINS. The version string as returned by SELECT vERSION() (as a char array) and the major.minor version number (as a flost) have been added to the ConnectionClass structure. Dave Page
