Hi hackers! Recently, one administrator asked me how to monitor the progress of his ALTER TABLE... ALTER COLUMN TYPE bigint.
That leads me to believe that consumers might benefit from having an API to track the table change process. PFA draft patch adding number of tuples (tuples_processed) that was read from the altered table. Thoughts? -- Best regards, Kirill Reshke
