Hi Sridhara,

For an incremental backup, you can use pgBackRest.

Please consider adding this feature to PostgreSQL.

 

Use Case:

When deleting a large number of records with constraints and triggers PostgreSQL is exceptionally slow.

 

Suggested change:

I believe a way to speed this processes up would be to offer an option a user could “turn on” prior to doing the delete. 

 

Example:  set delete-no-roll-back=true

 

Now as PostgreSQL deletes rows it literally deletes them one at a time as though the user was only deleting a single row.  This means that if cancel were executed on a delete action then it would only roll back the current row that PostgreSQL was in the process of deleting.  Example:  if you had 10 million row to delete and then pressed cancel after three minutes maybe 5 million are deleted.


You seem to be asking for an unlogged transaction, but that doesn't have anything to do with efficiently deleting rows.
