Don't share options
with a reference type column
Sharing `options` causes some unexpected behavior. If `limit: 2` is
specified, this means that 2 bytes integer for a reference id column and
2 chars string for a reference type column. Another example, if
`unsigned: true` is specified, this means that unsigned integer for a
reference id column, but a invalid option for a reference type column.
So `options` should not be shared with a reference type column.

* Don't share options between reference id and type columns
|
||||
|
||||
When using a polymorphic reference column in a migration, sharing options
|
||||
between the two columns doesn't make sense since they are different types.
|
||||
The `reference_id` column is usually an integer and the `reference_type`
|
||||
column a string so options like `unsigned: true` will result in an invalid
|
||||
table definition.
