Maximum Postgres connections
Hi! I’m using Neon on the free plan with the pooled endpoint (pgBouncer). I saw in the docs that pgBouncer supports up to 10,000 client connections, but I couldn’t find what the actual maximum number of Postgres connections is for the free plan. Could you clarify what the max active database connections are when using the pooled endpoint on the free tier?
