I'm trying to create a pod with Postgres. After initialize, the Pod has to execute the following command:

    "lifecycle": {
      "postStart": {
        "exec": {
          "command": [
            "export", "PGPASSWORD=password;", "psql", "-h", "myhost", "-U", "root", "-d", "AppPostgresDB", "<", "/db-backup/backup.sql"
          ]
        }
      }
    },     

Without these command the pod works perfectly.

I get the following status:

NAME              READY     STATUS         RESTARTS   AGE
postgres-import   0/1       ExitCode:137   0          15s

I get these events:
