Re: How to get current timeline of host in postgres 10.4? - Mailing list pgsql-admin
Hi Shreeyansh
I have executed the below query on master. But it is giving output like below
postgres=# select pg_current_wal_lsn();
pg_current_wal_lsn
--------------------
0/4B17D198
(1 row)
In slave side it is saying timeline 6
ubuntu@platform1:~$ psql -h "localhost" -F' ' -c 'IDENTIFY_SYSTEM' 'dbname=replication replication=true' -U postgres
systemid | timeline | xlogpos | dbname
---------------------+----------+------------+--------
6567260231287314481 | 6 | 0/4B1786E0 |
How can I get the timeline from the output of the query in master?
