Is that the file with in large friendly letters says: DO NOT EDIT THIS
FILE!

It says: It has been GENERATED by Gen_fmgrtab.sh
         from ../../../src/include/catalog/pg_proc.h

So you need to add it to src/include/catalog/pg_proc.h

Obviously if you want it to appear in pg_amproc you probably also want
to change src/include/catalog/pg_amproc.h

Have a nice day,
