I would think that NONUNIQUE should be the default, and you should have
to specify something special to also disable unique indexes. Arguably,
unique indexes are actually an implementation detail of unique
constraints. Disabling a performance-based index doesn't cause data
corruption, whereas disabling an index created as part of unique
constraint can allow invalid data into the table.

Just my $.02 ...
