I believe the values that actually get inspected at runtime are the
tgdeferrable and tginitdeferred fields in pg_trigger. The columns in
pg_constraint are just copies of these.
It is not real clear to me whether it should be allowed to alter the
deferrability status of a foreign-key constraint --- is that in the spec?
