The official C++ client API for PostgreSQL, providing a modern interface to interact with PostgreSQL databases.
libpqxx is the official C++ client API for PostgreSQL, providing a modern, type-safe interface for interacting with PostgreSQL databases. It allows developers to execute queries, manage transactions, and handle connections using contemporary C++ idioms, building on top of PostgreSQL's standard C library (libpq). The library solves the problem of low-level database access by offering a higher-level, more intuitive C++ abstraction.
C++ developers building applications that require PostgreSQL database connectivity, especially those using modern C++ standards (C++20 or later) and needing type-safe database operations.
Developers choose libpqxx because it is the official, well-maintained C++ API for PostgreSQL, offering a robust and modern alternative to raw libpq usage. Its unique selling point is seamless integration with C++ features like exceptions, templates, and iterators, making database programming more natural and less error-prone.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Leverages C++20 features for compile-time type checking in queries, as shown in examples like tx.query<std::string, int>(), reducing runtime errors and improving code reliability.
Supports multiple query styles, including efficient streaming for large datasets and single-value fetches, allowing developers to optimize performance based on use cases.
Provides transaction classes like pqxx::work with automatic rollback on exceptions, ensuring data integrity without manual cleanup code.
As the official C++ API for PostgreSQL, it is actively maintained and includes comprehensive documentation on Read The Docs, with built-in HTML generation from source headers.
Building requires PostgreSQL development headers and libraries, and linking can be error-prone, especially with version mismatches or on Windows, as noted in the troubleshooting section.
Tied exclusively to PostgreSQL; offers no abstraction layer for other databases, limiting flexibility for projects that might need to switch backends.
Version 8.x requires C++20, which can be a barrier for legacy codebases or teams using older compilers, forcing upgrades or sticking with older libpqxx versions.
