## Description
As in the past we have seen the corruption of postgres DB which is being
used for temporal we want to make sure we have a retry mechanism in
place if:
1. `APPSMITH_DB_URL` is pointing to postgres url
2. Postgres is waiting in recovery mode
As per local testing when the docker container is abruptly shutdown via
`docker rm -f {container_name}` or `docker kill {container_name}` or
even via docker desktop we end up in state where postgres goes into
recovery state.
logs:
```
2024-09-27 08:02:49 backend stdout | SQL State : 57P03
2024-09-27 08:02:49 backend stdout | Error Code : 0
2024-09-27 08:02:49 backend stdout | Message : FATAL: the database system is starting up
```
Currently we have implemented polling mechanism, but we will keep
looking for better alternative here if we can opt for.
Note:
1. With release dump this is taking ~300sec to get out of that state and
start accepting the connections.
2. With the existing implementation without retries server dies down
within 60sec.
```
INFO exited: backend (exit status 1; not expected)
INFO gave up: backend entered FATAL state, too many start retries too quickly
```
