Re: Enhance Makefiles to rebuild objects on map file changes

It looks weird. From https://www.postgresql.org/message-id/1CA8625F-AA41-4ED2-B60F-E28AC71F37DC%40highgo.com, I don’t see the attachment of the patch file. However, the email in my Inbox has the attachment.

Try to resend the attachment.
