Not quite, you'll lose the referential action information if you don't
include info out of tgfoids on the pk table's triggers and you'll lose the
deferment info if you don't pay attention to tgdeferrable and
tginitdeferred. In your case you're not using those, but...
There have been messages in the past about how to get the reference
information.  You should be able to find a function or something in
the archives :)
