Percona Server for PostgreSQL is a binary-compatible, open source drop-in replacement for PostgreSQL {{pgversion}}. It functions identically to upstream PostgreSQL, allowing you to migrate seamlessly between the two.
In addition to upstream functionality, Percona Server includes enhancements that enable advanced extension capabilities.
- Storage Manager (SMGR) API exposure, which allows PostgreSQL extensions to integrate custom storage managers. This change was inspired by the following patchset :octicons-link-external-16: introduced to the community.
- WAL Read/Write API exposure, which allows extensions to hook into WAL read and write operations.
These enhancements serve as the foundation for Percona-authored extensions, such as pg_tde, which enables data-at-rest encryption.
For details about available extensions, see the Percona-authored extensions topic.
