Quick Fix: Database Connection

The Issue

You tried to connect with blockscout user, but the custom explorer backend uses the explorer user.

Correct Command

# ✅ Correct - for custom explorer backend
PGPASSWORD='L@ker$2010' psql -h localhost -U explorer -d explorer -c "SELECT 1;"

Quick Steps

1. Test connection:

   PGPASSWORD='L@ker$2010' psql -h localhost -U explorer -d explorer -c "SELECT 1;"
   

2. Run migration:

   cd explorer-monorepo
   PGPASSWORD='L@ker$2010' psql -h localhost -U explorer -d explorer \
     -f backend/database/migrations/0010_track_schema.up.sql
   

3. Restart server:

   pkill -f api-server
   cd explorer-monorepo/backend
   export DB_PASSWORD='L@ker$2010'
   ./bin/api-server
   

4. Verify:

   curl http://localhost:8080/health
   

Two Separate Systems

• Blockscout: User blockscout, Password blockscout, DB blockscout
• Custom Explorer: User explorer, Password L@ker$2010, DB explorer
