It is PostgreSQL to select the node whether "sync" or "async".
pgsql RA displays a result of the following SQL.
select application_name,upper(state),upper(sync_state) from
pg_stat_replication;
So, at first, please watch PostgreSQL's log.
Possibly the data may become inconsistent.
You can resolve the inconsistency in the following operation.

Hi,
i am trying to run postgresql cluster with streaming replication using pgsql RA
and pacemaker ..
i succeded once, master was as PRI, slave HS:sync, failover worked as it should
(slave become master) ..
but after some tests something went wrong and i don't know what and why and how
to get it back working ... now when i start crm, master is PRI, but slave gets
into HS:ASYNC state .. and when master fails, and slave gets into HS:alone state
can somebody please give me hint what should i do or what should i look for?
Thanks a lot for any help
