According to the docs at
is a one-arg version in 9.6.
I've been watching this thread since I noticed it a few days ago. I
have a system on 9.6 with replication, where the standby uses
`archive_mode: always` so that I can run WAL-E backups from there
instead of from the master. I'm a little worried about my backup
integrity now (It sounds like this might be a "it usually works"
situation). Also, WAL-E currently uses the no-arg pg_stop_backup, but
I was contemplating offering a patch to use non-exclusive backups when
available, both to avoid stopping the standby and also to generate a
tablespace description (which WAL-E requires when restoring with
tablespaces). Just thought I'd offer a real use-case for the
non-exclusive-mode functions on 9.6.
I don't have an opinion on the urgency of back-porting a fix, but if
pg_stop_backup(boolean) allows for inconsistent backups, it does sound
like a problem on 9.6 too.
