One way I have approached this problem is: 1) Use PgAdmin attempt the change.
2) Examine the error report PgAdmin displays that identifies which dependent views are preventing your progress. 3) Wrap your original DDL from step 1 within the DROP and CREATE DDL associated with the closest dependent view. 4) Return to step 1 and repeat until step 1 succeeds. With multiple iterations of this procedure, you will incrementally grow a DDL script that drops dependent views in the correct order, eliminating dependencies, and then recreate them in the proper order, respecting dependencies. When this procedure got old, I started using a script created using pg_dump and pg_restore, as initially outlined here: https://www.postgresql.org/message-id/55c3f0b4.5010...@computer.org and with a correction noted here: https://www.postgresql.org/message-id/0456dfda-4623-1331-7dca-e3cff914357b%40computer.org -- B ----- Original Message ----- From: "Elson Vaz" <elson...@gmail.com> To: pgsql-general@lists.postgresql.org Sent: Tuesday, January 30, 2018 8:40:45 AM Subject: Alter view with dependence without drop view!
