This is possible, but I guess I should try and reproduce the actual problem
with the same archive_command script and a CIFS mount just to see what
happens. Perhaps the real root of the problem is elsewhere, it just seems
strange since the archive_command is the only postgres related process that
accesses the CIFS share. More later.
