PrismaClientInitializationError: Can't reach database server
This means Prisma can't establish a connection to your database at all — usually a wrong `DATABASE_URL`, a paused/suspended Neon project, a missing `?sslmode=require`, or a firewall blocking the connection.
PostgreSQL error: password authentication failed for user
The username/password in your connection string doesn't match what the database expects. Regenerate or re-copy the full connection string from your provider's dashboard (Neon, Supabase, etc.) rather than typing it by hand.
PostgreSQL error: too many connections for role
You've hit your database's connection limit — extremely common in serverless environments (Vercel functions, Lambda) where each invocation can open a new connection. Use a connection pooler (Neon's pooled connection string, or PgBouncer) instead of connecting directly.
Prisma error P2021: The table does not exist in the current database
Prisma's client was generated against a schema that includes a model whose table was never actually created in this specific database — usually because migrations haven't been applied to this environment, or you're connected to the wrong database entirely.
PostgreSQL error: FATAL: sorry, too many clients already
This is a server-wide connection limit, distinct from the per-role "too many connections for role" error — the entire database instance has hit its max_connections ceiling from all roles combined. It's the same root fix as the per-role version: use a connection pooler in serverless environments, and make sure you're not creating a new PrismaClient per request.
