[google-cloud-sql-discuss] PostgreSQL: checkpointer process was terminated by signal 9: killed

Hello,

in the last couple weeks my Postgres instance went down a few times. I found the following messages in the logs, but can't put my finger on what the root cause may be.

Is this some known issue? What else can I do to troubleshoot?

[16-1] db=,user= LOG: checkpointer process (PID 645146) was terminated by signal 9: Killed
[17-1] db=,user= LOG: terminating any other active server processes
[2-1] db=,user= WARNING: terminating connection because of crash of another server process
[3-1] db=,user= DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
[4-1] db=,user= HINT: In a moment you should be able to reconnect to the database and repeat your command.
