Vote for Postgres extensions

[kiwicopple]

This issue is for tracking requests/demand for Postgres Extensions. Give a thumbs up if you want an extension added.

Please refrain from adding comments unless you are adding an extension which isn't already listed.

[kiwicopple]

plv8 - https://github.com/plv8/plv8

[kiwicopple]

released 🚢

[ozum]

@kiwicopple, could you please hide messages when a requested extension is added, so we can easily see the remaining ones?

[kiwicopple]

PL Python

edit: this cannot be supported on Supabase because it is an untrusted extension. See here for more details
https://github.com/orgs/supabase/discussions/2239

[skwaugh]

Was support for this recently dropped? Can't find it in a new pg13 supabase project...which means it is not enabled during initial build. Is this temporary or the norm going forward?

[chrichrichri]

Any news on the plpython extension we would really love to use this in our project.

[burggraf]

@inian Any word on this python extension?

#2239 (comment)

[shah]

PL Java would be great - https://github.com/tada/pljava.

Also, ARG based build which would enable/disable certain plugins might also be helpful.

Great work by the way, love the Dockerfile.

[kenahrens]

Timescale - https://github.com/timescale/timescaledb

[derfurth]

It would be great to have the complementary timescaledb_toolkit as well (it's under the same license), as is provides all of the hyperfunctions to query the time-series.

[georgewritescode]

Following up to also note that timescaledb_toolkit would be very helpful given it has many of the functions required to use timscaledb. Also referenced here: https://github.com/orgs/supabase/discussions/17108

[encima]

Timescale-toolkit is under the TSL License and cannot be offered by Supabase (or any Database-as-a-service)

[riderx]

Timescale is useless in supabase environments…
That why I made a PR to have a columnar db alternative:
https://github.com/orgs/supabase/discussions/679#discussioncomment-7791898
please have a look and if that fit your use case upvote it

[bitnom]

IMO some alternative to timescale should have been used. The licensing is bad, and the version you can use in supabase cloud is not good.

[shah]

plpgsql_check for linting and validating SQL code quality.

[kiwicopple]

Added 👍

[felixyz]

wal2json

[dragarcia]

Added via Supabase Postgres v13.3.0.

[Takashiidobe]

I would like to see pg_cron on here, although I don't know about the licenses.

[kiwicopple]

Added 👍

[psolymos]

PL/R would be great! https://github.com/postgres-plr/plr and https://access.crunchydata.com/documentation/plr/8.3.0.18/

[Vadorequest]

https://github.com/furstenheim/is_jsonb_valid seems useful for enforcing JSON schemas in columns using the JSON type.

It's not in the Database > Extensions yet, I suggest it is added.

It seems to be more performant than its https://github.com/gavinwahl/postgres-json-schema counterpart. (from the author)

[chipilov]

FYI, since the https://github.com/gavinwahl/postgres-json-schema extension is implemented in PL/pgSQL, you can enable it manually in your instance by running its script against your db: https://github.com/gavinwahl/postgres-json-schema/blob/master/postgres-json-schema--0.1.1.sql (you just need to remove/replace the references to @extschema@, since that's only available for extensions).

Postgres Message Queue (PGMQ) extension

A lightweight message queue. Like AWS SQS and RSMQ but on Postgres.

Documentation: https://tembo-io.github.io/pgmq/

Source: https://github.com/tembo-io/pgmq

Features

• Lightweight - No background worker or external dependencies, just Postgres functions packaged in an extension
• Guaranteed "exactly once" delivery of messages to a consumer within a visibility timeout
• API parity with AWS SQS and RSMQ
• Messages stay in the queue until explicitly removed
• Messages can be archived, instead of deleted, for long-term retention and replayability

[hamishirving]

Also https://github.com/tembo-io/pg_vectorize by the Tembo guys

[ShravanSunder]

PostgresML

I'm curios if postgresml can be isntalled in supabase https://postgresml.org/docs/guides/developer-docs/installation
It seems to be a good complement to pgvector and uses pg vector underneath

[occidens]

pg_rational

Generally useful for precise rational arithmetic, but especially useful for efficiently applying user-defined ordering to table rows.

[riderx]

Hydra columnar

Hydra is open source, column-oriented Postgres. You can query billions of rows instantly on Postgres without code changes. Parallelized analytics in minutes, not weeks.

[riderx]

They columnar extension could be a good alternative to timescale who have a licence too limitative in cloud

[riderx]

here is PR: supabase/postgres#849

[therealpurplemana]

Would like to see this available alternative as an to Timescale for this use case on Supabase!

[hamishirving]

https://github.com/tembo-io/pg_vectorize

Create and search embeddings from your pg tables

[therealpurplemana]

Please add two votes:

a) pg_similarity: https://github.com/eulerto/pg_similarity
b) timescaledb

[riderx]

timescaledb is already in it, but only the apache licence

[magick93]

https://github.com/apache/age has finally updated their pg version support.

[medina474]

temporal_tables

This extension provides support for temporal tables. System-period data versioning (also known as transaction time or system time) allows you to specify that old rows are archived into another table (that is called the history table).

pgvecto.rs

Like pgvector but better and faster.

We are currently experiencing some bottlenecks with pgvector when it comes to filtering: pgvector/pgvector#259

We have tested pgvecto.rs locally and it works surprisingly well. This would actually be game changing!

---

pgvecto.rs is a Postgres extension that provides vector similarity search functions. It is written in Rust and based on pgrx. Read more at 📝our blog.

ogr_fdw

It allows to access up to 83 distinct spatial file formats or databases with a Foreign Data Wrapper relying on the vector half of the GDAL library.

[coryt]

Would it be possible to get a version of postgres with the data wrapper extensions included? Specifically I would be looking for the airtable fdw.

[imor]

Airtable FDW is already available in the wrappers extension: https://supabase.github.io/wrappers/airtable/

SipHash via pghashlib extension.

Or a new SIMD extension by Supabase Devs based on Defending Against Hash Flooding.

This protects Supabase from "hash flooding" denial-of-service attacks (HashDoS)
