Avoid retrieval of CHECK constraints and DEFAULT exprs in data-only dump
Those extra queries are not necessary when doing a data-only dump. With
this change, this means that the dependencies between CHECK/DEFAULT and
the parent table are not tracked anymore for a data-only dump. However,
these dependencies are only used for the schema generation and we have
never guaranteed that a dump can be reloaded if a CHECK constraint uses
a custom function whose behavior changes when loading the data, like
when using cross-table references in the CHECK function.
