Hello,

the ODBC-driver has an option to emulate updateable cursors (default "on"). AFAIK are updateable cursors supported since PostgreSQL version 8.3. Does the driver have to emulate updateable cursors with current PostgreSQL-versions or should this option be disabled for newer PostgreSQL releases?

I tried to figur it out myself, but the code is very tricky on the whole configuration stuff... :-S

regards
Chris

*Updatable Cursors* in psqlodbc means *updatable result set*. You can
call SQLSetPos(.., SQL_UPDATE/SQL_DELETE) or SQLBulkOperations() but
unfortunately psqlodbc driver doesn't support positioned update using
CURRENT OF CURSOR.
