+# datatypeCase (experimental)
+
+Converts datatypes to upper- or lowercase.
+
+This option doesn't yet support all types of data types:
+
+- multi-word data types with non-datatype keywords like `timestamp with time zone` are not fully supported - the `WITH` will be cased as a normal keyword
+
+## Options
+
+- `"preserve"` (default) preserves the original case.
+- `"upper"` converts to uppercase.
+- `"lower"` converts to lowercase.
