I'm not really sure how to read that binary file.

I have uploaded to an s3 bucket and made it public.
Anyone should be able to access that file

it's  2GB

If you have a link to a documentation of how I can read that file and get the stacktrace, I would be glad to give it a read.

Thank you for taking the time to have a look.

I'm not sure how to enable core dump with the docker image.

I've seen some documentation where the db is started with pg_ctl anc a "c" flag. I couldn't find anything on enabling it on the docker image.

in my data folder, I have a huge core file (8 GB). Would it be possible that it is the core dump file generated after the segfault?

you can check a create time

Hi


If I can help in any ways, please let me know.
I don't mind trying things, like I said, the bug happens about every 2
days.

This is a bug, but from your bug report isn't possible to detect any information.

Can you enable core dump generating, and can you send a core dump?

Regards

Pavel

Cheers!
