You just broke initdb with this cleanup. :-)

Running in noclean mode.  Mistakes will not be cleaned up.
The files belonging to this database system will be owned by user "zozo".
This user must also own the server process.

The database cluster will be initialized with locales  COLLATE:  hu_HU.utf8  CTYPE:    hu_HU.utf8  MESSAGES: C

The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "hungarian".

initdb starts postgres --single, that doesn't do BackendInitialize(),
only PostgresMain(). So, you need InitializeTimeouts() before
the RegisterTimeout() calls in PostgresMain and the elog(PANIC)
must not be in InitializeTimeouts() if called twice.
