Column value gets reset to default on server restart

Hello, we are facing a really weird error. Our postgis instance is running inside docker, we have mounted a volume for data persistence. Now, when our system restarts due to power failure, all of our data is intact except the one column in our table which gets reset to its default value. We don't know what is the issue since only this column of a table from the whole db gets reset.

I have attached the latest docker logs upon server restart, kindly guide me to help fix this issue.

We are using the latest postgis docker image.

STATEMENT: CREATE EXTENSION postgis;

It's interesting,

based on your log : "Skipping initialization"
on the other hand, the repo initialization uses the CREATE EXTENSION IF NOT EXISTS postgis; SQL command!
- see https://github.com/postgis/docker-postgis/blob/master/14-3.3/initdb-postgis.sh#L17
  - or https://github.com/postgis/docker-postgis/blob/master/initdb-postgis.sh#L17

So Is it possible that you are using an extra initialization code in your codebase?

all of our data is intact except the one column in our table which gets reset to its default value. We don't know what is the issue since only this column of a table from the whole db gets reset.

I have no better theory than the extra initialization code.
