I bumped into the good-old 100-byte limit of the (v7?) tar format on
which pg_basebackup is depending. It is unlikely in the real world but
I think it is quite common in developping environment.  The tablespace
directory path in my dev environment was 110 chacters-long.  As small
as 10 bytes but it's quite annoying to chip off that number of bytes
from the path..
