Authentik Embedded Proxy Outpost error when connecting to PostgreSQL via PGBouncer

### Describe the bug

Error in logs:

> {"error":"failed to setup database: failed to connect to PostgreSQL: failed to connect to `user=authentik database=authentik`: ip:port (dns name): server error: FATAL: unsupported startup parameter: search_path (SQLSTATE 08P01)","event":"failed to setup application","level":"warning","logger":"authentik.outpost.proxyv2","timestamp":"2025-11-18T17:34:45Z"}

Error when trying to open the application through a proxy provider:

In my case, I am using cloud database and I can't set `IGNORE_STARTUP_PARAMETERS: search_path` in PGBouncer config.
