Sync PG_VERSION file in CREATE DATABASE. An OS crash could leave PG_VERSION empty or missing. The same symptom appeared in a backup by block device snapshot, taken after the next checkpoint and before the OS flushes the PG_VERSION blocks. Device snapshots are not a documented backup method, however. Back-patch to v15, where commit 9c08aea6a3090a396be334cc58c511edab05776a introduced STRATEGY=WAL_LOG and made it the default.
