Add postgres pod status check for k8s tests in CI

[pankajkoti]

It appears we have a flaky Kubernetes test that failed in PR #1313. As shown in the error log here, the PostgreSQL pod did not reach the ready state and instead entered an error status. Since the cause of the error status is unclear, this PR introduces a status check for the PostgreSQL pod to ensure it becomes fully running and healthy. If the pod enters an ERROR state, we now run a kubectl describe command on the pod to capture the event logs for debugging. The test will also exit with an error code of 1 to prevent further execution.
