Hi, 
I supposed "pg_control version number:" is related to pg version, but fresh pg 15 instance  pg_controldata shows 1300:

$ initdb -V
initdb (PostgreSQL) 15.1
$ initdb
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "en_US.UTF-8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".

Data page checksums are disabled.

initdb: warning: enabling "trust" authentication for local connections
initdb: hint: You can change this by editing pg_hba.conf or using the option -A, or --auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    pg_ctl -D /pgdata/pgsql/15/data -l logfile start

$ pg_controldata -V
pg_controldata (PostgreSQL) 15.1
$ pg_controldata /pgdata/pgsql/15/data | grep "pg_control version number:"
pg_control version number:            1300
