Welcome to pgrx v0.19.0. Among other things, this brings support for Postgres v19beta1.

As usual, install cargo-pgrx with cargo install cargo-pgrx --version 0.19.0 --locked, and if you want Postgres 19beta1 support you'll also need to run cargo pgrx init. And make sure to update your crate dependencies with cargo pgrx upgrade.
