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.

Hi Community,

While working on the upgrade from GB18030 to GB18030-2022, I updated two GB18030-related map files. However, rebuilding PostgreSQL did not recompile anything, which led me to discover that the Makefiles under src/backend/utils/mb/conversion_procs were missing dependency rules between NAME.o and the corresponding map files.

This patch adds the necessary dependencies to ensure that when a map file changes, the corresponding .o file is rebuilt accordingly.

I have done tests for every Makefile I changed in a way like:

# make a change to a map file
$ make
# a .o got rebuilt
$ make # make again without map file change
# nothing re-compiled
