-> The name of this project always makes me grin: PIGSTY is actually an acronym, standing for Postgres In Great STYle! It's a Postgres distribution that includes lots of components and tools out of the box in areas like availability, deployment, and observability. The latest release pushes everything up to Postgres 16.2 standards and introduces new ParadeDB and DuckDB FDW extensions.
