Hello,
I have a table with a large number of records (millions), on which the
following should be performed:
1. Retrieve a set of records by a SELECT query with a WHERE condition
2. Process these in the application
3. Delete them from the table

Maybe you can just do begin; delete from ..... WHERE ... RETURNING *;,
process records and issue COMMIT after processing?
