Bug reference: 18963
Logged by: Mathias Panzenböck
Email address: grosser(dot)meister(dot)morti(at)gmx(dot)net
PostgreSQL version: 17.0
Operating system: Linux
Description:

Foreign key constraints have the option to list the columns that should be
changed in ON DELETE/ON UPDATE SET NULL/SET DEFAULT. For the ON DELETE case
these columns can be inspected with pg_catalog.pg_constraint.confdelsetcols,
but there is no such column for the ON UPDATE case. Is this an oversight?
There are also other constraint parameters that I couldn't find (NULLS
DISTINCT for UNIQUE constraints and index_parametrs for several kind of
constraints), but I haven't searched too long for those yet.
