Re: How to start slave after pg_basebackup. Why min_wal_size and wal_keep_segments are duplicated

Hi!

>In addition to my most recent questions:
>What are you trying to achieve?

I want to create  hot standby async server using 

/etc/init.d/postgresql stop
mv /var/lib/postgresql/12/main /var/lib/postgresql/12/mainold
pg_basebackup --write-recovery-conf -D /var/lib/postgresql/12/main
chmod --recursive --verbose 0700 /var/lib/postgresql/12/main
chown -Rv postgres:postgres /var/lib/postgresql/12/main
/etc/init.d/postgresql start

>In other words why do a pg_basebackup if you have a standby receiving WALs?

I dont receive WALs.
