Detailed Description

In-place alter handler context.

This is a superclass intended to be subclassed by individual handlers in order to store handler unique context between in-place alter API calls.

The handler is responsible for creating the object. This can be done as early as during check_if_supported_inplace_alter().

The SQL layer is responsible for destroying the object.
