Hi Gilles,
So it seems this bug is related to the credcheck extension, updating credcheck to the latest version 4.3.0 did not help,
when removing credcheck extension from the shared_preload_libraries parameter the bug disappears.

I will open a bug request on github for credcheck.

Thank you all very much for your help.

Summary

PostgreSQL server crashes with a segmentation fault when executing ALTER USER CURRENT_USER WITH PASSWORD in PostgreSQL 16.10 and 16.11. The crash results in immediate termination of the backend process and forces a full instance restart.


Hi Andril,

I think the problem might comes from the credcheck extension. Please upgrade to version 4.3 of credcheck. Several possible crash have fixed since v3.0.

Best regards.
