Hi,
Does anyone know why forgein key constraints are not enforced when
updateing multiple tables using a combination of views and rules?
This doesn't seem to be a major problem as I can specify the columns
in question as not null and this will produce an ExecInsert error if
the data is not present in my insert.
However, it seems to me that it would be better to be able to rely on

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
