Tom, thanks, as usual awesome support on the 3rd Sunday in
Advent ...
This is what my 8.3 manual says:
conkey │ int2[] │ pg_attribute.attnum │ If a table constraint, list of columns which the constraint constrains │
From that I wouldn't have figured it'd apply to foreign keys
as well. So I assume it is fair to say that "foreign keys
are one type of table constraint", right ?
Thanks again,
Karsten
