Add a new field `Up` to **add column** migrations:
```json
{
"name": "03_add_column_to_products",
"operations": [
{
"add_column": {
"table": "products",
"up": "UPPER(name)",
"column": {
"name": "description",
"type": "varchar(255)",
"nullable": true
}
}
}
]
}
```
The SQL specified by the `up` field will be run whenever an row is
inserted into the underlying table when the session's `search_path` is
not set to the latest version of the schema.
The `up` SQL snippet can refer to existing columns in the table by name
(as in the the above example, where the `description` field is set to
`UPPER(name)`).
