feat: Honour postgresql_version on SUSE and handle transactional updates - #222
Conversation
On SUSE the role installed the postgresql-server meta package, so postgresql_version had no effect, and the version check read the noarch postgresql package, whose version is a bare "18". The second converge then failed with "Setting version 13 while 18 is installed". SLE 15 SP7's meta package installs postgresql17-server while that package reports 18. Install postgresqlNN-server on SUSE, default to 18 there, and read the installed major from the server packages. Extract the major with an anchored regex so a version without a dot is read correctly on every distribution. tests_versions now also runs on SUSE. Handle reboots for transactional update systems such as SLE 16.1 Immutable. A package install there is only staged into a new snapshot and is not live until reboot. Detect transactional systems and, when the packages were staged or are not live yet, reboot if postgresql_transactional_update_reboot_ok is true, notify if false, and fail if it is unset.

Add sentence that this variable is related to managed nodes that have OS with transactional updates.
set_vars always sets __postgresql_is_transactional, so the conditions need no default filter. Say in the argument spec that the reboot variable applies only to systems with transactional updates. Signed-off-by: HVSharma12 <harshvardhan.sharma@suse.com>

Add a usage example for the reboot option.
Show how to set postgresql_transactional_update_reboot_ok, for example in a short playbook variable block. As per path instructions, README.md must “Include usage examples for new functionality.”

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Read the SUSE major version from the server package name.
On the SLE 15 SP7 case described in the PR context, postgresql17-server reports package version 18. These lines therefore identify an installed PostgreSQL 17 server as version 18. A request for 17 fails the mismatch check, while a request for 18 can pass that check despite the installed 17 server. Extract the SUSE major version from the matched package name; retain the package-version check for platforms where its existing contract applies. Ansible exposes the package name and package version as distinct facts. (docs.ansible.com)

Stop role execution when a staged package is not live and reboot is declined.
If installation stages a new server package and postgresql_transactional_update_reboot_ok is false, this task notifies the user but execution continues to initdb and service setup. The server package is not live until reboot, so those tasks can fail instead of completing the documented notify-only path. End the host’s role work after the notice, or defer package-dependent tasks until the next run. SUSE documents that a transactional update becomes active after reboot. (documentation.suse.com)

Enhancement: Honour postgresql_version on SUSE, and support transactional systems.
Reason: On SUSE the role installed the postgresql-server meta package, so postgresql_version had no effect, and the version check read a bare "18" as "1". The second run then failed with "Setting version 13 while 18 is installed". On a transactional system (SLES 16.1 Immutable) a package install is only staged until reboot.
Result: The role can be re-run on SUSE and installs the requested version. tests_versions now also runs on SUSE. The full test suite passes on SLE 15 SP7, SLE 16.0, SLE 16.1, Leap 15.6 and Leap 16.0. With the variable true the role reboots and continues, with false it only notifies, and unset it fails. Verified on SLES 16.1 Immutable. Other platforms are unchanged.
