In which cases is it recommended to use the PostgreSQL database?

PostgreSQL is recommended in the following cases:

• When a reliable and scalable relational database with support for complex queries is needed.
• If advanced features such as transactions, full-text search, spatial data (PostGIS) are required.
• For projects where compliance with SQL standards and high compatibility are important.
• When extensibility is needed — the ability to add custom data types, functions, and operators.
• When open-source license and active community support are important.

Example: a web application with large data volume requiring complex analytical queries and high reliability is well suited for PostgreSQL.
