Welcome to pgrx v0.16.1. This is a relatively minor release but does add support for Postgres v18, released on September 25, 2025.

As always, install/update cargo-pgrx with cargo install cargo-pgrx --version 0.16.1 --locked. Then run cargo pgrx update in all your extension crates.

To pick up Postgres v18, you'll need to run (at least) cargo pgrx init and then add the pg18 feature flag to your extension's Cargo.toml.
