I have a foreign key constraint that I'd like to alter. I'd rather not

Is it ok to set confupdtype to 'c' in pg_constraint (and will this be
all that's needed) or is it safer to drop and recreate the constraint?


I don't think that's going to work, you'd probably need to change the
function associated with the trigger involved too.  It's probably safer to
do the drop and create.

ok, thanks.
