I am using postgresql 12. As part of streaming replication setup, I run pg_basebackup on the slave which copies the database from master to slave. But the database is huge and it takes around 2 to 3 days for the pg_basebackup to finish. When pg_basebackup is running, a huge number of wal files are generated on the master which occupies a lot of space (even though it is for 2-3 days, disk space is low). Is there any other way to start replication without using pg_baseback?
