Database Connection Pool Exhaustion
Requests start failing with 'too many connections' or connection timeout errors. Error appears after app runs for a while or under load. Connection pool is exhausted.
Database has limited connections. Without proper connection management, connections leak and pool becomes exhausted.
Error Messages You Might See
too many connections
connection timeout
connection pool exhausted
ERROR: FATAL connection limit exceeded
Common Causes
- Connections not being closed after use
- Long-running transactions holding connections
- Creating new client per request instead of reusing
- Async operations not awaiting properly
- Connection pool size too small for load
How to Fix It
Reuse Supabase client instance:
// Good - single instance
const supabase = createClient(URL, KEY);
export default supabase;
// Bad - creates new client each request
const client = new createClient(URL, KEY);Keep transactions short. Use connection pooling mode in Supabase Settings.

Get HelpFrequently Asked Questions
How many connections does Supabase allow?
Default 5 for free tier, increases with plan. Check Settings > Database for current limit.
Should I create new client per request?
No, reuse single client instance. Client handles connection pooling internally.
