The underlying cause is likely roughly similar, to wit failure to read
/usr/share/zoneinfo/UTC (or the Postgres-private equivalent file).
The parent process would long since have cached the zone data in its
memory, but this error is in a parallel worker process, which'd have
to read the file for itself during startup.
What's causing that I can't say. It doesn't look like we log the
errno anywhere when failing to read a zone file :-(
