I'm not entirely convinced by Simon's theory that this is already fixed,
because there are some points that you didn't mention.
First off, the thing isn't *supposed* to remove the latest .backup file;
that one, and its .done file, should stick around until your next
successful pg_stop_backup call. pg_stop_backup removes all but the
just-created .backup file (if they have .done files, showing they've
been archived). No other operation touches them at all.
Second, the bug Simon mentions consists in trying to create the .ready
file for the new .backup file twice during pg_stop_backup. If the
archiver is fast enough to have pushed out the .backup file already,
this would result in there being both a .ready and a .done file for the
.backup file. If that's what you see, then manually removing the .ready
file should clear the problem --- I wouldn't recommend manually removing
either .done or .backup. If that's *not* what you see, then we have
another problem to deal with. Please report back.
