Migrates fofo.scheme_item from composite ...</title><description>&lt;div&gt;&lt;strong&gt;amit – 1 file(s) modified&lt;/strong&gt;&lt;br/&gt;Add scheme_item windowing migration script.&lt;br /&gt;
&lt;br /&gt;
Migrates fofo.scheme_item from composite (scheme_id, catalog_id) PK to&lt;br /&gt;
surrogate id BIGINT, adds audit columns, swaps the old uniqueness to&lt;br /&gt;
the 4-column window key, adds a date-driven lookup index, and installs&lt;br /&gt;
BEFORE INSERT/UPDATE triggers that enforce start&amp;lt;=end, containment in&lt;br /&gt;
parent scheme window, and non-overlap within (catalog_id, scheme_id).&lt;br /&gt;
&lt;br /&gt;
Step 4b drops the legacy UNIQUE scheme_catalog (scheme_id, catalog_id);&lt;br /&gt;
without this the windowing feature is functionally blocked.&lt;br /&gt;
&lt;br /&gt;
