Bug description

When deploying PostgreSQL 18 with postgresql_data_checksums: false, the data checksums are enabled.

Expected behavior

Data checksums are disabled when postgresql_data_checksums: false and during upgrade from 17 -> 18.

Steps to reproduce

1. Deploy cluster with postgresql_version: 18 and postgresql_data_checksums: false
2. SELECT name,setting FROM pg_settings WHERE name = 'data_checksums';

Installation method

Command line

System info

Debian 13
Autobase from Git.

Additional info

Current logic assumes that data checksums are disabled by default. Since PostgreSQL 18, data checksums are enabled, unless explicitly disabled. Therefore, Autobase needs to be updated to specify --no-data-checksums for PostgreSQL >= 18, when the postgresql_data_checksums: false, and during upgrade.
