your patch doesn't work with updatable views because they don't have
ctid columns....

ERROR:  column "ctid" does not exist
STATEMENT:  update vfoo set des_cta = des_cta || ' - prueba' where
current of foo;
ERROR:  current transaction is aborted, commands ignored until end of
transaction block

is this sane behavior? to accept create cursors for update on views
and then failing to update "where current of" and rollback the entire
transaction?

comments?
