I realized Lars said it was x86_64/Linux, but I'm hoping to hear back with more
details:
What OS version?
Is it a VM of some type ?
How did you install postgres? From a package or compiled from source?
grep -r HAVE_CLOCK_GETTIME /usr/pgsql-13/include
Send the exact command and output you used to run the query?
Why does your explain output have IO timing but not Buffers: hit/read ?
