LGTM, thanks! I believe @ImreSamu is away and has limited availability at the moment, but I'll hold off on merging this PR until later this evening US/Eastern time after I've had a chance to run some smoke tests. Thanks again!

[ImreSamu]

Thank you! I tested with ./update.sh and everything looks good.

One comment: PG18 + PGDATA has changed, and we should also document this on our side. ( README.md ? )

• https://github.com/docker-library/docs/tree/master/postgres#pgdata
  • Change PGDATA in 18+ to /var/lib/postgresql/MAJOR/docker docker-library/postgres#1259

The key point:
* For version 18 the path is : /var/lib/postgresql/18/docker

It can maybe be handled with a new column into the _dockerlists_${optimized}.md tables 🤔

Like:

| DockerHub image | Dockerfile | OS | Postgres | PostGIS | PgData |
| --------------- | ---------- | -- | -------- | ------- | ------ |

In my opinion it would be sufficient to document the difference by placing comments in the "Supported Environment Variables" section of README.md that highlights the PGDATA difference new in v18 along with a link to the upstream explanation of it that provides more details.

I'll merge this PR as I'd like for it not to go stale. We can address the PGDATA note in docs in a follow-up PR 👍
