-- Fix script for settings table column issues
-- Run this in your PostgreSQL database to resolve the schema mismatch

-- Step 1: Rename the old column to the new name
ALTER TABLE settings RENAME COLUMN company_logo_path TO company_logo_filename;

-- Step 2: Add any missing columns (these will be skipped if they already exist)
