# Database Authentication Issue Fixed

## Problem
- PostgreSQL authentication was failing with error code 28P01 "password authentication failed for user 'quixotic'"
- The docker-compose.yml had default password `quixotic123` but .env.docker had different password `GGkM0a6r7pw3F65ZvYbbuOgbt7gO2AoW3JynEk7m9Go=`
- Secondary issue: table creation conflicts due to SERIAL sequences being created multiple times

## Solution
1. **Password sync**: Removed postgres container and volume to reset with correct password from .env.docker
   ```bash
   docker compose down postgres
   docker volume rm quixotic_postgres-data
   docker compose up postgres -d
   ```

2. **Table creation fix**: Modified database.ts to check table existence before creating:
   - Added proper table existence check using information_schema
   - Removed `CREATE TABLE IF NOT EXISTS` which wasn't handling SERIAL sequences properly
   - Added logging for better debugging

## Commands used
```bash
docker compose down postgres
docker volume rm quixotic_postgres-data  
docker compose up postgres -d
docker compose build quixotic-app
docker compose up quixotic-app -d
```

## Result
- Database authentication working
- No more table creation conflicts
- App starts successfully with "Database tables already exist" message
