Hi all,

I have a question.
As far as I see,constraints are stored into PG database ordinarily
as follows.

  1) RelationAddRawConstraints() converts each raw constaint
      to bin form.
  2) StoreRelCheck() converts the bin form to src form and store
      them into pg_relcheck tuples.

Is pg_relcheck.rcsrc equivalent to the original raw constraint ?
