PostgreSQL Query Cursor for Node.js

pg-cursor is a specialized extension for the `node-postgres` library, enabling Node.js applications to utilize PostgreSQL result cursors. This functionality allows developers to fetch large query results incrementally in manageable chunks, effectively preventing out-of-memory issues that can arise when loading massive datasets into memory all at once. The library is currently at version 2.19.0 and is actively maintained as part of the broader `node-postgres` ecosystem, with updates typically released to ensure compatibility, address bugs, or introduce minor enhancements. Its primary differentiator lies in providing an efficient, streaming approach to data retrieval from PostgreSQL, which is crucial for high-performance applications dealing with extensive database tables. A key technical requirement is its exclusive compatibility with the pure JavaScript `pg` client, explicitly stating it does not support native PostgreSQL bindings.
