bowerbird is complaining here with the tests of pg_basebackup:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=bowerbird&dt=2021-12-08%2004%3A52%3A27

tar: Cannot execute remote shell: No such file or directory
tar: H\\:/prog/bf/root/HEAD/pgsql.build/src/bin/pg_basebackup/tmp_check/t_010_pg_basebackup_main_data/backup/tarbackup2/base.tar:
Cannot open: I/O error
tar: Error is not recoverable: exiting now

This comes from init_from_backup() via the tar_command. I am not sure
what to think about this error. Perhaps this is related to the
environment.

+$ENV{TAR} ||= 'tar';
+$ENV{LZ4} ||= 'lz4';
+$ENV{GZIP_PROGRAM} ||= 'gzip';
This means that the default is to assume that those commands will be
always present, no? But that may not be the case, which would cause
the tests of pg_basebackup to fail in 010_pg_basebackup.pl. Shouldn't
we at least check that the command can be executed if defined and skip
the tests if not, in the same fashion as LZ4 and GZIP?
