Subject: Fix documentation of pg_start_backup and pg_stop_backup functions.
X-Git-Tag: REL_12_BETA1~194
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b804c1837b55722369d30be707738c098a75cd7a;p=thirdparty%2Fpostgresql.git

Fix documentation of pg_start_backup and pg_stop_backup functions.

This commit adds the description that "non-exclusive" pg_start_backup
and pg_stop_backup can be executed even during recovery. Previously
it was wrongly documented that those functions are not allowed to be
executed during recovery.

Back-patch to 9.6 where non-exclusive backup API was added.
