Both of these are pretty useful signals to be able to handle from a
background worker.

  • SIGINT allows doing something special when pg_cancel_backend is
    called on the pid of your background worker
  • SIGCHLD is useful when your background worker spawns other processes
    and wants to get notified when they crash/finish.

Both of these are pretty useful signals to be able to handle from a

- `SIGINT` allows doing something special when `pg_cancel_backend` is
  called on the pid of your background worker
- `SIGCHLD` is useful when your background worker spawns other processes
  and wants to get notified when they crash/finish.

Update version to 0.10.0 (#1280)
3d1c8e3 
This is the final release of v0.10.0. Thanks everyone for the beta
testing, pull requests, issues, and patience.

As always, install `cargo-pgrx` with `cargo install cargo-pgrx --locked`
and update your extension Cargo.toml files to use the `0.10.0` pgrx
dependencies.

This release includes support for Postgres 16RC1. Support for the
previous betas has been removed. As such, a fresh `cargo pgrx init` is
required.
