Conflicts

In case the node is subscribed to multiple providers, or when local writes happen on a subscriber, conflicts can arise for the incoming changes. These are automatically detected and can be acted on depending on the configuration.

The configuration of the conflicts resolver is done via the pglogical.conflict_resolution setting.

The resolved conflicts are logged using the log level set using pglogical.conflict_log_level. This parameter defaults to LOG. If set to lower level than log_min_messages the resolved conflicts won't appear in the server log.
