How to use postgres via sqlx without libpq

[banool]

Hi,

Is there a way to use sqlx without the system having libpq installed? For example, does it support using the rust-postgres library instead?

Thanks!

SQLx doesn't use libpq. We have our own bespoke implementation of the Postgres protocol, similar to rust-postgres but lower level so we're not beholden to their API design.

Wow that's awesome to hear, so there is no dependency on any external dynamically linked library?

If you use the tls-native-tls feature on Linux it will dynamically link OpenSSL, but you can enable the vendored feature of the native-tls crate to have it built from source and statically linked:

[dependencies]
native-tls = { version = "0.2", features = ["vendored"] }

Alternatively you can use the tls-rustls feature which uses RusTLS.

Perfect, yeah we use the rustls option already to avoid the OpenSSL dep. Thanks!
