postgresconf webinar example code

https://postgresconf.org/conferences/postgres-webinar-series/program/proposals/pgx-build-postgres-extensions-with-rust

This is the complete set of examples I intend to demonstrate during the above webinar.

System Dependencies

First off, you need the following software to build this extension:

• A toolchain capable of building Postgres

  On Ubuntu, this is the full set of dependencies

  sudo apt install -y clang llvm make curl bison flex zlib1g zlib1g-dev pkg-config libssl-dev libreadline-dev`
  

• Rust (curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh)
• The cargo-pgx cargo subcommand (cargo install cargo-pgx)

Once these tools are installed, you need to run cargo pgx init in order to locally install the three versions of Postgres pgx requires. Depending on your internet connection and computer, this step may take 5-10 minutes.

Building this Extension

Finally, clone this repo and build it:

$ git clone https://github.com/zombodb/postgresconf.git
$ cd postgresconf
$ cargo pgx run pg12

This will drop you into a psql shell to the cargo-pgx-managed Postgres 12, in a database named postgresconf.

Simply create the extension:

CREATE EXTENSION postgresconf;
