It will probably just show some library names and addresses, but so
far we don't even know if this is crashing in LLVM or in PostgreSQL
code so that'd be a clue.  Maybe function names would appear if you
set up DEBUGINFOD_URLS, depending on where you got your packages from:

Hoping to find time to repro this later on a cloud host.  If this is a
cloud host, can you tell me which cloud, instance type, memory size
etc?  I had already been trying on some local ARM hardware with no
luck (same versions but diferrent OS, so going to try making more
things match you case)...
