Add support for pg_authid

Add entries for pg_authid catalog table in all versions

These .rs bindings files are auto-generated (and we only store them in git to appease docs.rs builds).

Instead of hand-editing them, please add the appropriate header files to each of the .h files here: https://github.com/tcdi/pgx/tree/master/pgx-pg-sys/include

[nikkhils]

@eeeebbbbrrrr that's much easier, thanks. Will re-submit. However, who will add the entries in the Rust files? Should I keep the ones I have added around or remove them in this PR and only have the .h changes?

[eeeebbbbrrrr]

It happens automatically during compilation. Like I said, those .rs files only exist to make docs.ra website happy.

[nikkhils]

@eeeebbbbrrrr great. I have re-submitted with just the header file changes

[eeeebbbbrrrr]

can you please do one other thing and update your fork from what's currently on tcdi/pgx? I screwed up our git history, and that's why this PR is showing 204 files changed.

Done!

@eeeebbbbrrrr is there anything else I need to do here? Also if everything is ok, when will this be merged into dev and when it will be part of a release? TIA.

@nikkhils Thanks! I'll merge this and you can expect it in our next release. :)
