A DBI-compliant R interface to PostgreSQL, rewritten in C++ for improved performance and reliability.
RPostgres is a DBI-compliant R package that provides a modern interface to PostgreSQL databases. It solves the problem of efficient and reliable database connectivity in R by offering parameterized queries, automatic resource cleanup, and improved performance over older solutions. The package is designed for seamless integration with the R data analysis workflow.
R developers and data scientists who need to interact with PostgreSQL databases for data retrieval, manipulation, and analysis within the R ecosystem.
Developers choose RPostgres for its modern C++ implementation, which ensures better performance and memory safety, along with full DBI compliance for consistent database operations. Its simplified build process and focus on reliability make it a preferred alternative to older PostgreSQL interfaces in R.

Full support via `dbSendQuery()` and `dbBind()` enables secure, SQL-injection-proof queries, as highlighted in the README for safe execution.
Ensures connections and result sets are managed automatically, preventing memory leaks and simplifying code maintenance.
Saves ~5 ms per query compared to alternatives, offering tangible speed gains for small to medium datasets, as documented in the README.
Relies on system libpq, reducing installation complexity and external dependencies for smoother setup.
Exclusively supports PostgreSQL, making it unsuitable for projects using other databases like MySQL or SQLite.
Requires libpq to be installed on the system, which can complicate deployment in controlled or minimal environments.
The ~5 ms per query savings may not justify adoption for large queries or infrequent operations where overhead is negligible.
