Hi,
Isn't it better to forbid the conbination of the options "-D -", "-F t" and
"-X stream" in pg_basebackup? This is obviously invalid setting and the docs
warns this as follows. But currently users can specify such setting and
pg_basebackup can exit unexpectedly with an error.
-----------------------
If the value - (dash) is specified as target directory, the tar contents will
be written to standard output, suitable for piping to for example gzip.
This is only possible if the cluster has no additional tablespaces.
-----------------------
