+------------------------------------------------------------------------

+------------------------------------------------------------------------
+DO $$
+BEGIN
+  IF NOT EXISTS (
+    SELECT 1
+    FROM pg_type t
+    JOIN pg_namespace n ON n.oid = t.typnamespace
+    WHERE t.typname = 'PdfTitle'

+-- 3) Safely replace PdfCategory enum values:
+--    Strategy:
+--      a) change column type to text
+--      b) normalize existing text values (map legacy names -> new names)
+--      c) create new enum type with desired values
+--      d) cast column from text -> new enum
+--      e) drop old enum type and rename new enum to PdfCategory
+------------------------------------------------------------------------
+
+-- a) Convert column to text (so we can freely rewrite strings)
+ALTER TABLE "PdfGroup"
+  ALTER COLUMN "category" TYPE text
+  USING "category"::text;
+
+-- b) Normalize the textual values
+-- mapping rules:
+--   'ELIGIBILITY' -> 'ELIGIBILITY_STATUS'
+--   'CLAIM'       -> 'CLAIM'
+--   'OTHER'       -> 'OTHER'
+--   'CLAIM_STATUS'-> 'CLAIM_STATUS'   (if somehow present as text)
+-- Any unknown legacy values will be coerced to 'OTHER'
+UPDATE "PdfGroup"
+SET "category" =
+  CASE
+    WHEN LOWER(TRIM("category")) = 'eligibility' THEN 'ELIGIBILITY_STATUS'
+    WHEN LOWER(TRIM("category")) = 'claim' THEN 'CLAIM'
+    WHEN LOWER(TRIM("category")) = 'other' THEN 'OTHER'
+    WHEN LOWER(TRIM("category")) = 'claim_status' THEN 'CLAIM_STATUS'
+    WHEN LOWER(TRIM("category")) = 'claim status' THEN 'CLAIM_STATUS'
+    ELSE 'OTHER'
+  END;

+-- c) Create the new enum type (with a temporary name)
+DO $$
+BEGIN
+  IF NOT EXISTS (
+    SELECT 1
+    FROM pg_type t
+    JOIN pg_namespace n ON n.oid = t.typnamespace

+      'CLAIM',
+      'ELIGIBILITY_STATUS',
+      'CLAIM_STATUS',
+      'OTHER'
+    );
+  END IF;
+END$$;
+
+-- d) Cast the column from text to the new enum
+ALTER TABLE "PdfGroup"
+  ALTER COLUMN "category" TYPE "PdfCategory_new"
+  USING ("category")::"PdfCategory_new";
+
+-- e) Drop the old enum type (if present) and rename the new type to PdfCategory.
+-- First drop old type if it exists
+DO $$
+BEGIN
+  IF EXISTS (
+    SELECT 1 FROM pg_type t JOIN pg_namespace n ON n.oid = t.typnamespace
+    WHERE t.typname = 'PdfCategory'
+  ) THEN
+    EXECUTE 'DROP TYPE "PdfCategory"';
