[MohithS04]

Hello Pallavi, Can you once check the newly created ddl_organizations_1_.sql table

[MohithS04]

Since, I am unable to create a Test case Table and pork it in script-library/tests. So, I've written the Test cases in an existing PR.
Test Cases for Organization Table Migration

Test 1: rename applied
DO $$
BEGIN

SELECT 1 FROM information_schema.columns
WHERE table_schema = 'virginia_dev_saayam_rdbms'

ASSERT EXISTS (
    SELECT 1 FROM information_schema.columns
    WHERE table_schema = 'virginia_dev_saayam_rdbms'
      AND table_name   = 'organizations'
      AND column_name  = 'is_collaborative'
      AND data_type    = 'boolean'
), 'T1: is_collaborative missing or wrong type.';

END $$;

Test 2: new column added
