Definition
Plain language
A widely used free database program that stores and organizes data for applications.
As stated in the literature
PostgreSQL, an open-source relational database; appears in agent tool-use benchmarks such as MCPMark as a backend workload that agents must query and manipulate correctly.
Also called: PostgreSQL
Why it matters: As a widely used database, it makes a realistic test of whether an agent can handle the data tasks that real applications depend on.
For example, an agent might be asked to query a Postgres database to find all customers who ordered last month and update their loyalty points correctly.
