Pgrx: Build Postgres Extensions with Rust
- levkk 5mo agoAmazing project that spawned entire companies. We used it to build postgresml[0] and most Postgres extensions are built on top of it these days. [0] https://github.com/postgresml/postgresml https://github.com/postgresml/postgresml
- pratio 5mo agoAmazing, I didn't know this existed.
- braiamp 5mo agoThe domain for the org has expired and now it's a parking hosts. I don't know how maintained it is.
- Icathian 5mo agoPostgresml closed up shop, the guy you're replying to was one of the key players there. Pgrx is trucking right along, and gaining speed at the moment.
- K0nserv 5mo agoI built https://github.com/k0nserv/plid https://github.com/k0nserv/plid with Pgrx and had a great time. I did have to scale back some of the magic (dropping derive PostgresType etc), but even so the support pgrx provides is excellent. I also talked to the maintainers a bit in discord and they were super helpful. The one downside of custom extensions is that you aren’t, AFAIK, able to use them with many hosted Postgres installs, notably AWS RDS.
- Wicher 5mo agoOr rather – one of the downsides of many hosted Postgres installs, notably AWS RDS, is that you're not able to use the extensions you want.
- K0nserv 5mo agoIndeed, that's a much better formulation.
- infogulch 5mo agoMaybe one of the reasons why hosted postgres often disallows extensions is due to security concerns from loading arbitrary machine code on a shared host. I wonder if pgrx changes the calculus here.
- phamilton 5mo agoFrom the same org as pgrx is https://github.com/pgcentralfoundation/plrust https://github.com/pgcentralfoundation/plrust, which _is_ supported on RDS (but not Aurora). Since it's a procedural language, you can't do things like create a new index implementation or something else super low level. But there's still a lot you _can_ do. Like implement a custom comparator for a custom type and then use that type in a btree index.
- jpshastri 5mo agoSupabase is an interesting middle ground here — it runs on managed Postgres but gives you access to a curated set of extensions (pg_cron, pgvector, unaccent, PostGIS etc.) without needing to build your own. We used unaccent + GIN indexes for fuzzy city search and it worked well. Still not the same as arbitrary custom extensions, but covers a lot of practical use cases that RDS won't touch.
- setr 5mo agoRDS also has a curated set of extensions? https://docs.aws.amazon.com/AmazonRDS/latest/PostgreSQLReleaseNotes/postgresql-extensions.html https://docs.aws.amazon.com/AmazonRDS/latest/PostgreSQLRelea... Which includes literally all 4 extensions you’ve mentioned. Every managed service does this, specifically because they need to blacklist extensions that touch on the managed parts of it — eg filesystem
- tracker1 5mo agoIf I need to do fuzzy location searches, I've thought about just matching geohash locations... even if doing multiple sets and collating them... Note: this was in consideration for something like Scylla or Dynamo.
- awesomeMilou 5mo agoI thought this was abandoned?
- dukepiki 5mo agoLast release was two weeks ago. pgrx is actively maintained.
- tracker1 5mo agoThe maintainers for this project are pretty nice all around. Very knowledgeable and as helpful as anyone could ask.
- dukepiki 5mo agoPlanetScale's internal extensions -- Insights, Traffic Control, and pg_strict -- are all built in pgrx. Number of memory unsafety and race conditions I've had to debug in production in a year of use: zero. pgrx is fantastic.
