Describe the bug (please write manually, do not ask AI to summarize)

What happened:
When attempting to perform a backup using the Databasus agent, the base backup fails with the following error:

upload basebackup: upload failed with status 500: (pg_basebackup stderr: pg_basebackup: initiating base backup, waiting for checkpoint to complete pg_basebackup: checkpoint completed pg_basebackup: write-ahead log start point: 644/CEF3AA08 on timeline 37 pg_basebackup: error: can only write single tablespace to stdout, database has 3 )

Steps to reproduce

  1. curl -L -o databasus-agent "http://172.16.88.45:4005/api/v1/system/agent?arch=amd64" && chmod +x databasus-agent
  2. Configure postgresql.conf ( wal_level = replica, archive_mode = on, archive_command = 'cp %p /opt/databasus/wal-queue/%f.tmp && mv /opt/databasus/wal-queue/%f.tmp /opt/databasus/wal-queue/%f'
  3. Configure pg_hba.conf (host replication all 127.0.0.1/32 md5)
  4. run "pg_ctl reload -D /var/lib/pgpro/ent-18/data/"
  5. run ./databasus-agent start --databasus-host=http://172.16.88.45:4005 --db-id=aa2e6c20-4698-4729-9f59-66807e9666e2 --token=5d8dc2d6c827423db2856cc1c7234cf4 --pg-host=localhost --pg-port=5432 --pg-user=MyUserHere --pg-password=MyPasswordHere --pg-type=host --pg-host-bin-dir=/opt/pgpro/ent-18/bin --pg-wal-dir=/opt/databasus/wal-queue
  6. The backup starts automatically according to the schedule configured in Databasus UI. Within 5-10 minutes after the scheduled start, the following error appears in the agent logs
