Document pgBadger exit codes

[jsabater]

Dear Gilles,

First of all, merci beaucoup for your amazing pgBadger. Truly.

Second, I've been trying to find the exit codes of pgBadger in the documentation pages of pgBadger but I have not been able to. I was so sure I had read about it in the past that I was not sure whether to post this request or not. It's just to control exit codes in the script called from a cron job that runs pgBadger daily with all the required parametres (nothing out of the ordinary).

Could you please point me at the right direction?

Thanks in advance.

pgBadger exit code:

• 0: on success.
• 1: die on error.
• 2: if it has been interrupted using ctr+c for example.
• 3: the pid file already exists, maybe another process is already started, or can not be created.
• 4: no log file was given at command line.

Commit 2a99d51 fixes the documentation about return codes and also some wrong return code at some places.
