Usually, or by "pg_basebackup" or by "rsync" as described in PostgreSQL
Wiki.
Right now, I'm doing via pg_basebackup.
Nothing extraordinary.

When using rsync:

rsync -e "ssh -2 -C -p slave_ssh_port" --progress --partial -az
/pgsql/9.6/master_data_folder/*
superuser_name(at)$slave_host:/home/pgsql/9.6/slave_data_folder/ --exclude
postmaster.pid --exclude postgresql.conf --exclude pg_log

When using pg_basebackup:

/usr/pgsql-9.6/bin/pg_basebackup -h master_host -p master_port -D
/home/pgsql/9.6/master_data_folder -R -S slot_name -X stream -P -d "
user=superuser_name password=superuser_pass sslmode=require "

Of course, this is inside a bash script with variables at right places
to make script generic as needed to make it works with dozens of
databases...
