process rep [local] sending backup "pg_basebackup base backup"
but no data is written. Looks like wal sender is hurt. max_wal_senders
= 3, I wonder if this is the reason for the stall. How to eval if this
is set to low? Thanks.
It may be that pg_basebackup is waiting for a checkpoint to complete.
Try adding -cfast.
