🆚 CouchDB vs. PostgreSQL

Apache CouchDB is an open-source, document-oriented NoSQL database that stores data as JSON documents and exposes a RESTful HTTP API for application access.

It features multi-version concurrency control, masterless replication with bi-directional sync, automatic conflict detection, map-reduce views for indexing and queries, pluggable storage engines, and supports clustering with horizontal scaling across multiple nodes.

PostgreSQL, also known as Postgres, is a powerful open-source object-relational database system that extends SQL with features for storing structured, semi-structured and geometric data.

It supports ACID transactions, multiversion concurrency control (MVCC), advanced indexing types (GiST, GIN, BRIN), native JSON/JSONB with indexing, extensibility through custom types and functions, full-text search, foreign data wrappers, and geospatial queries via PostGIS.
