Subject: Running rsync backups in pg15

Hi,

In PG14 and earlier, there is no requirement to keep database connection while rsync is in progress. However, there is a change in PG15+ that requires rsync to be while we have the same database session open that executes SELECT pg_backup_start('label'). This change requires a rewrite of existing scripts we have.

Currently (pg14):

                In bash script (run from cron)

  1.  psql Select pg_start_backup
  2.  rsync
  3.  psql Select pg_stop_backup


In pg15 and later:


In bash script (run from cron)



psql

Select pg_start_backup

! run-rsync-script

Select pg_stop_backup

It can be done, but it makes it ugly to check errors and so forth that occur in the rsync script.

Anybody found an elegant way of doing this?

Thank you in advance for your ideas.
