pg_extension_updater — Automatic extension updater

The reviewed catalog snapshot records version 3.4, kind preload, and implementation language C. Install and validate the declared extension dependencies first: pg_extension_base. The curated compatibility set is 16,17,18; confirm the exact build against the target server.

CREATE EXTENSION "pg_extension_updater";
SELECT extversion
FROM pg_extension
WHERE extname = 'pg_extension_updater';

The upstream project is associated with Snowflake; verify its current support, license, packaging, and deployment boundary from the linked source.

The curated lifecycle is active. Pin the reviewed build and verify maintenance status before adoption. The official material contains an experimental, deprecated, unsupported, or explicit warning boundary; read it in full and test failure cases before non-lab use.

Before production use, review the linked control/SQL or provider documentation, verify privileges and compatibility, and test the actual API and failure behavior on the target PostgreSQL build.
