Question
App platform and postgresql connection pool wont work

Asked by fulloap3+digital
I am successfully running a python app in app platform, and it reaches the managed Postgres database just fine.
I have created a connection pool in the database to increase the connection limit, but when updating the connection parameters in the python app, I just get timeouts when trying to reach the database connection pool.
What I have tried:
- The app is whitelisted in the trusted sources of the database
- The connection string to the pool works fine! I have the same python app running outside Digital Ocean and works fine!
- When I skip the connection pool and go straight to the database, everything works fine!
- I have tried attaching the database to the App in App Platform.
- Searched in the forum and others are having the same issue with different programming languages.
I can’t deactivate trusted sources in the database, since it is required for the project.

Hi there,
UPDATE:
PostgreSQL connection pools are now supported in App Platform using trusted sources.
For example if you connect your DigitalOcean database to an App Platform app as “mydb” component, and that database has a connection pool “mypool”, you can use bindable variables to automatically integrate it into your app as a trusted connection. An example environment variable would be:
See the documentation.
Hope this helps.
