Enum CompatVersion 

pub enum CompatVersion {
    V14,
    V15,
    V16,
    V17,
    V18,
    V19,
}

A PostgreSQL major version that rupg.compat_version can name.

Version 19 is the native answer. Versions 14 to 18 are shims over the answer of version 19. See spec/05-compatibility.md.

Implementations

impl CompatVersion

pub const ALL: [CompatVersion; 6]

All versions, oldest first.

pub const NATIVE: CompatVersion = CompatVersion::V19

The native version. A shim maps the answer of this version to an older one.

pub const fn major(self) -> u32

The major version number.

pub const fn server_version_num(self) -> u32

The value of server_version_num for this version. The shims report the minor release of the shim pin.
