Tests are also slightly refactored in order to remove duplicated code. Execution of postgres -C is used for restore_command retrieval (if -r is passed) as being suggested. Otherwise everything works as before.

The new patch is much smaller (less than 400 lines) and works as advertised.
There's a typo "retreive" there.

These lines look a little suspicious:
char postgres_exec_path[MAXPGPATH],
postgres_cmd[MAXPGPATH],
cmd_output[MAX_RESTORE_COMMAND];
Is it supposed to be any difference between MAXPGPATH and MAX_RESTORE_COMMAND?

Besides this, patch looks fine to me.
