Version Numbering

Starting with PostgreSQL 18, Percona uses the following format:

MAJOR.MINOR.PATCH

For example:

18.1.1

Where:

• MAJOR = The upstream PostgreSQL major version (e.g. 18 → PostgreSQL 18)
• MINOR = The upstream PostgreSQL release number
• PATCH = Percona’s internal build number (specific to packaging or Percona-only updates)

Release type	Version example	What changes?
First Percona build	18.0.1	Initial Percona build on upstream 18.0, build #1
Percona-only update	18.0.2	Build #2 on the same upstream 18.0
Upstream patch/feature	18.1.1	Upstream release → MINOR bump to 1, PATCH reset to 1
Next Percona build	18.1.2	Build #2 on upstream 18.1

The above versioning is only applicable to PSP 18.x.x as it is the only Percona forked server. The third digit is always PSP’s build number, never an upstream patch. If you see it go from …1 → …2 this means a PSP-specific update was shipped.

Since PPG 13 to 16 are pure community versions, only the first 2 digits scheme is used for them.
