While using 'Inspector' to introspect MySQL and PostgreSQL databases
dialects, I've noticed some slight variation:

For MySQL, a UNIQUE table constraint also shows up as an Index (with
unique=True).

Ditto PostgreSQL (as of 0.9.8).

Looking at the current HEAD, it appears that PostgreSQL has some
support for additionally annotating indexes with
'duplicates_constraint', but there is no similar support for MySQL.

Will 'duplicates_constraint' support be added to MySQL as well?
Will that appear in 0.9.9?
