Oleksii Kliukin 1c61280d70 Fix path to scripts subdirectory in configuration files. 2015-09-08 16:10:42 +02:00
Oleksii Kliukin da132ca1fc Do not rely on env vars for superuser role name.

Oleksii Kliukin a5f2ab6f88 Better SIGCHLD handling, use correct user name. 
- Defer SIGCHLD processing until the later stage in order to allow
  subprocess to run its own reaping of children and return the correct
  exit code from the process called.

- When changing the password at startup, do not assume the user postgres.

Oleksii Kliukin 33b5e1b22e Make sure is_leader is False does not trigger the leader re-check. 2015-07-17 15:22:21 +02:00
Oleksii Kliukin 11004f8c48 Be more robust on callbacks when cluster is down. 
For 'on_stop' or 'on_restart' callbacks we cannot
call is_leader, because the cluster would be stopped.

Instead, call is_leader before running a callback.
In addition, make the call_nowait more robust by handling
the exceptions related to the DB cluster unavailability.
