Simply cast `u32 as i32` and pass it through SPI to do this by other means. While it is an incredibly bad idea to do so, unfortunately that means we cannot rely on the conversion being `unsafe`, as there is no way we would make SPI unsafe. That leaves no persuasive argument for not providing From.

pgrx v0.11.2 is a minor release which - makes available the storage-related API, thanks to @silver-ymz in #1409 - deprecates the `Oid::from_u32_unchecked` API... because it is actually possible to do via casting in a *query*, which makes it effectively impossible for us to not wind up providing it via some other safe API, since the source is also an easily-Copied type. Thus you can now simply use `From::from` for it. Thanks to @thomcc for this discovery, implemented by @workingjubilee in #1374 As usual, `cargo install cargo-pgrx --version 0.11.2 --locked` and be on your merry way! Thanks everyone!
