Compatible server default value in the models.

MySQL has no native boolean type. MySQL boolean type is just an alias
to tiny int type field. So MySQL returns '"1"' for `true` value and
'"0"' for false value. Instead of it, Postgres has native boolean type.
Thus with Postgres, reflection of a boolean type column default value will
return either 'true' or 'false'. Model must have compatible
`server_default` argument in columns definition.
