Fix dumping of DEFERRABLE/INITIALLY DEFERRED:

> The big problem is that while pg_dump's dump_trigger() looks at

pg_get_constraintdef should probably be looking at condeferrable and
condeferred in the pg_constraint row it's looking at.  Maybe something
like the attached.

(Added, output only non-default values.)
