Difference between PouchDB and PostgreSQL

1. PouchDB : PouchDB is an open-source, NoSQL, in-line database. It is designed after CouchDB, which is a NoSQL database that powers npm. It is written in JavaScript language. There is no need to perform queries over the network as PouchDB resides inside the browser and thus it makes it extremely faster. It stores data locally using IndexedDB and WebSQL in the browser. 2. PostgreSQL : PostgreSQL is a powerful, open-source Object-relational database system. It provides good performance with low maintenance efforts because of its high stability. PostgreSQL was the first DBMS that implemented multi-version concurrency control (MVCC) feature.
