Обсуждение: pg_contraint: 'action code' ?

Hi,

where are the 'action code' (type char) of foreign keys defined for ON
DELETE resp. ON UPDATE for the actions NO ACTION, RESTRICT, CASCADE, SET
NULL, SET DEFAULT in pg_contraint?

In the manual (8.2) it is mentioned but not explained.

Thank You
Felix

Per the comment in pg_constraint.h:

/*
 * Valid values for confupdtype and confdeltype are the FKCONSTR_ACTION_xxx
 * constants defined in parsenodes.h.  Valid values for confmatchtype are
 * the FKCONSTR_MATCH_xxx constants defined in parsenodes.h.
