postgresql core dump crashes timescale database

[mqueack]

What happened?
Database crashes in azure cloud, because "no space left on device".
data & wal device have 1GB
size of all tables is smaller than 500KB
1 Standby & Backup is configured
This problem is that two core dumps needed all space of PV and database crash.

Did you expect to see something different?

1. Where can i disable the core dump function in timescale helm
2. Where is it possible to find more information why coredump is happening (SELECT seems to little information)
