How to properly setup PostgreSQL connection with TLS\SSL

[zwpdbh]

Is the some example to demostrate how to setup TLS\SSL when connecting to a postgres server?

I am new to this area and not sure how to setup TSL\SSL when connecting to a postgres server which enabled securit connection.
During production, when I set the DATABASE_URL, the app shows error with :

DATABASE_URL='postgres://$(DATABASE_USERNAME):$(DATABASE_PASSWORD)@$(DATABASE_HOST):$(DATABASE_PORT)/$(DATABASE_NAME)?sslmode=verify-full&sslrootcert=certs/US.pem'  cargo loco start -e production
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.29s
     Running `/home/zw/code/rust_programming/myapp/target/debug/backend-cli start -e production`
2025-01-19T12:55:57.345046Z  WARN app: loco_rs::boot: pretty backtraces are enabled (this is great for development but has a runtime cost for production. disable with `logger.pretty_backtrace` in your config yaml) environment=production
Error: DB(Conn(SqlxError(Tls("server does not support TLS"))))

At the app doesn't show anymore how to setup this.

The server i am connecting during production is hosted in Azure by some other group and could be turn off sercurity connection option.

• Applications that require certificate verification for TLS/SSL connectivity

Is there any suggestions how to do it? An working example would be wonderful :)
