Hmm ... conchuela has just found another problem with this test case:
ok 2 - detected live backend via shared memory
# Running: postgres --single -D /home/pgbf/buildroot/HEAD/pgsql.build/src/test/recovery/tmp_check/t_017_shm_gnat_data/pgdata template1
ack Broken pipe: write( 16, 'SELECT 1 + 1' ) at /usr/local/lib/perl5/site_perl/IPC/Run/IO.pm line 549.
I interpret this as "the single-user backend exited before we could stuff
'SELECT 1 + 1' down the pipe to it, and the Perl script is not expecting
to get a write failure there".
regards, tom lane
