Welcome to pgrx v0.15.0. This begins a new series for pgrx that includes
support for Postgres 18. As of this release, that means Postgres
18beta1.

This release does contain a few breaking API changes but they're largely
mechanical. Don't worry, the compiler will let you know!

As always, please install our CI tool with `cargo install cargo-pgrx
--version 0.15.0 --locked` and then run `cargo pgrx upgrade` in all of
your extension crates.

If you want to start working with Postgres 18beta1, you'll also need to
re-init your pgrx environment with `cargo pgrx init`. That will
automatically detect all the latest Postgres versions, including
18beta1.

At the top here, I'd like to thank @silver-ymz for the 18beta1 support.
It was a pleasant surprise to see that work come from the community --
it's no easy task to add a new Postgres version to pgrx!

That said, as Postgres 18 is currently beta, you should consider pgrx'
support for it as beta too. Please report any problems with 18beta1 (or
discrepancies with other versions) as GitHub issues.

Also, this release requires rust v1.88.0 or greater. `if-let` chains are
now a thing and we're not afraid to use them.
