Increase PostgreSQL concurrent connection limit for larger plans
complete

The default connection limit is 97. While increasing the connection limit is generally not advised for DB's with low memory, it may be okay to increase for the plans with higher RAM (>8GB)

We now provide higher connection limits of 197 connections for databases with greater than 6GB of memory, and 397 connections for databases with greater than 10GB of memory. These limits are applied automatically for newly created databases, but existing databases will require Render to perform a configuration change and restart on the database. Please email support@render.com to request that these limits be applied for existing databases exceeding the memory requirements.
See our documentation for more information: https://render.com/docs/databases#connecting-to-your-database

+1 we are hitting connection limits and I've used 300 as an appropriate connection limit for DBs this size (Pro 4GB 2CPU) and workload.
