Error: P1001: Can't reach database server
Full error message
PrismaClientInitializationError: P1001: Can't reach database server at `localhost`:`5432`
Solutionsource: official-docs \u2197
Prisma cannot open a TCP connection. 1. `systemctl status postgresql` — is the server running? 2. Check DATABASE_URL host/port — inside Docker use the service name, not `localhost`. 3. Check `listen_addresses` in postgresql.conf and `pg_hba.conf` for host entries. 4. Firewall / security group on port 5432.
