pg_dump:qemu: uncaught target signal 7 (Bus error) - core dumped - Mailing list pgsql-hackers

I found a scenario where, after firing the  wrong way of using the pg_dump command, not only server fail to start, 

But  later, I am not able to perform initdb/pg_ctl  as well 

"

PG v19 devel, Cluster running on default port=5432 

Run pg_dump (./pg_dump -Ft -s -c   -v -f postgres schema_clean.tar1)

edb@1a1c15437e7c bin]$ ./pg_dump -Ft -s -c   -v -f postgres schema_clean.tar1

pg_dump: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

 The correct way is to use 

./pg_dump -Ft -s -c   -v -f  schema_clean.tar1 postgres 

Is there any way we can generate some error messages?

regards,
