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?
