PostgreSQL vs SQLite: What are the differences?
Developers describe PostgreSQL as "A powerful, open source object-relational database system". PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. On the other hand, SQLite is detailed as "A software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine". SQLite is an embedded SQL database engine. Unlike most other SQL databases, SQLite does not have a separate server process. SQLite reads and writes directly to ordinary disk files. A complete SQL database with multiple tables, indices, triggers, and views, is contained in a single disk file.
PostgreSQL and SQLite can be categorized as "Databases" tools.
"Relational database", "High availability " and "Enterprise class database" are the key factors why developers consider PostgreSQL; whereas "Lightweight", "Portable" and "Simple" are the primary reasons why SQLite is favored.
PostgreSQL is an open source tool with 5.44K GitHub stars and 1.8K GitHub forks. Here's a link to PostgreSQL's open source repository on GitHub.
According to the StackShare community, PostgreSQL has a broader approval, being mentioned in 2739 company stacks & 2169 developers stacks; compared to SQLite, which is listed in 314 company stacks and 477 developer stacks.
