Title: Fix redshift schema dump.

Redshift does not support arrays, and dump was using `pg_index.indkey` which is unsupported `INT2VECTOR` type - so there is no way to compare it with normal integer.

Haven't found other workaround for now than removing the primary key check and setting it always to false. In mean time you can set it at the model level with `set_primary_key`.
