I've run across an inconsistent behavior when adding/removing unique constraints. I'm not sure if it is by intention? When I add a unique index to a table I use the name of the column I want to add it to. If I drop the index I need to know the name that was assigned?

Add a unique constraint to users.name

knex.schema.table('users', function (table) {
    table.unique('name');
})

Remove the previously added constraint

knex.schema.table('users', function (table) {
    table.dropUnique('users_name_unique');
})

I'm using knex 0.5.8.
