Database container log is got flooded by error messages

[Igorgro]

Hi, I have a Zulip installation which is based on compose file from this repository. Today I noticed that the log of database container is full of tons of this message:

zulip-database-1  | 2022-03-31 22:19:43.890 UTC [148] ERROR:  failed to re-find parent key in index "zerver_message_subject_cbe8c4b9" for deletion target page 280
zulip-database-1  | 2022-03-31 22:19:43.890 UTC [148] CONTEXT:  automatic vacuum of table "zulip.zulip.zerver_message"

I tried to google and found this solution https://dba.stackexchange.com/a/135885, but I am not sure is it safe to execute this commands. What should I do in this situation? Or maybe I can just ignore these messages?
