Message-ID: <CWXP265MB500957DD1918490CD4AB439EF7F5A@CWXP265MB5009.GBRP265.PROD.OUTLOOK.COM> (raw)

Many (but not all) DDL statements use the pattern IF EXISTS or IF NOT EXISTS. This is really useful if you want to create a re-start-able data model update script without needing to have PL/pgSQL blocks that has checks to see if it exists.

An example of a statement that doesn't implement this pattern in the CREATE POLICY statement.

Is there a plan to add this pattern to the rest of the DDL statements? Or could it be added to the CREATE/DROP POLICY statements?

Thanks,
Paul
