Hi,

would it be good idea to add new paragraph 5.3.7 to chapter 5.3
(Constraints) with at least information that there is something like
partial unique index and link to chapter 11.8 (Partial Indexes)?

Partial index can be used to enforce uniqueness in a way other constraints
cannot provide. Currently, it not easy to find this type of constraint as
not a lot of people would read through documentation on indexes when
looking for constraints.

Regards,

Tomas
