Hi Asif,
Thanks for new patches.
Patches need to be rebased on head. Getting a failure while applying the
0003 patch.
edb(at)localhost postgresql]$ git apply
v11/0003-Parallel-Backup-Backend-Replication-commands.patch
error: patch failed: src/backend/storage/ipc/ipci.c:147
error: src/backend/storage/ipc/ipci.c: patch does not apply
I have applied v11 patches on commit -
23ba3b5ee278847e4fad913b80950edb2838fd35 to test further.
pg_basebackup has a new option "--no-estimate-size", pg_basebackup crashes
when using this option.
[edb(at)localhost bin]$ ./pg_basebackup -D /tmp/bkp --no-estimate-size --jobs=2
Segmentation fault (core dumped)
--stacktrace
