Yeah, that was intentional. I wanted to avoid recursion again by
hitting ATExecAlterChildConstr() at the end of
ATExecAlterConstraintInternal(). Also, I realized the value doesn’t
matter since recurse = false is explicitly set inside the
cmdcon->alterEnforceability condition. I wasn’t fully satisfied with
how we handled the recursion decision (code design), so I’ll give it
more thought. If I don’t find a better approach, I’ll add clearer
comments to explain the reasoning.
