foreign key update and delete actions are not reflected in pg_constraint table

[AlexMesser]

FK's update and delete actions works fine, but not reflected in pg_constraint table.

Steps to reproduce:

CREATE TABLE "foo" ("id" INT PRIMARY KEY)

CREATE TABLE "bar" ("id" INT PRIMARY KEY, "fooId" INT)

CREATE INDEX "idx_fooId" ON "bar" ("fooId") 

ALTER TABLE "bar" 
     ADD CONSTRAINT "fk_foo_bar" 
     FOREIGN KEY ("fooId") REFERENCES "foo"("id") 
     ON UPDATE SET NULL
     ON DELETE SET NULL

SELECT "conname", "confupdtype", "confdeltype" FROM "pg_constraint"

results:

conname	confupdtype	confdeltype
fk_foo_bar	a	a

from the postgres docs:
confupdtype - Foreign key update action code: a = no action, r = restrict, c = cascade, n = set null, d = set default
confdeltype - Foreign key deletion action code: a = no action, r = restrict, c = cascade, n = set null, d = set default

Should be an easy fix, I'll take it on.

@AlexMesser we're fixing this in the master branch. @awoods187 does the fix need to be ported back to 2.1 too?
