Am I missing something or can't you just add another set of function pointers
to the PDO driver and statements like:
driver_methods = {
...
pg_copy_from, /* OR NULL IF NOT SUPPORTED */
pg_copy_to
};
statement_methods = {
...
pg_copy_to
};
Then if the driver does not implement it, throw an exception. Then, in the
future, these could be abstracted on a higher level for drivers that don't
support it by using lower level INSERT / SELECTS. The difference in the
abstraction being that the files would be on the client side, not the server.
The initial values would of course be NULL except fo the PostgreSQL PDO drivers.
Then call the functions as $pdo_obj->copyFrom(...) and $pdo_obj->copyTo(...) or
$pdo_stmt->copyTo(...)
