Creation of partial indexes

[andyparsons]

Hello- is there any way to create partial indexes with Lobos? Something like this:

CREATE UNIQUE INDEX favo_3col_uni_idx ON favorites (user_id, menu_id, recipe_id) WHERE menu_id IS NOT NULL;

CREATE UNIQUE INDEX favo_2col_uni_idx ON favorites (user_id, recipe_id) WHERE menu_id IS NULL;
