Bugfixes:

• SIGPIPE signal is now handled. Reported by Yuri Kurenkov.
• Error conditions encountered by remote agent are now reported correctly. Reported by Yuri Kurenkov.
• It is now possible to start taking more than one backup a second. Previously an attempt to do so resulted in an error. Reported by Daria Lepikhova.
• Waiting for Start LSN now happens after the parent backup is chosen, which allows us to error out earlier if there is no suitable parent.

Improvements:

• --force flag for restore in incremental mode now allows us to overwrite the contents of the directory specified by PGDATA in case of system ID mismatch. Previously this resulted in an error.
