Supabase Wrappers: An FDW Framework Written in RustForeign data wrappers (FDWs) provide a mechanism within Postgres to access data on remote/external systems, whether other SQL databases or flat files. Supabase has built Wrappers in an attempt to bring a myriad of FDWs under one roof (already including ones to integrate with Stripe, Firebase, and Airtable) and to make it easier to build more.

QUOTE: “The FDW interface also future-proofs Postgres. Instead of keeping up with the latest technological advances, Postgres can instead act as an interface whenever they develop. The recent advance in AI and ML is a great example of this: AI technology is developing faster than the time it would take to build a new 'AI database'. With a FDW, Postgres can become the interface to this technology and many other technological advances in the future.”

Faster PostgreSQL to BigQuery Transfers — The author, well known for his ‘1.1 Billion Taxi Rides’ database benchmarks, demonstrates how using ClickHouse to export Postgres tables to Parquet for importing into BigQuery is quicker than using compressed CSVs. A beautifully practical post and of obvious interest to anyone doing GIS work in particular.

sqld: A 'Server Mode' for libSQL/SQLite — This is a bit of an unusual one. Rather than using Postgres’s wire protocol in front of another database, this is essentially SQLite in front of the Postgres wire protocol (the idea being apps that use SQLite - or the libSQL fork of it, anyway - can continue to act as they already do, but are actually using Postgres behind the scenes).
