By referencing the respective git logs, I didn’t have too much difficulty identifying the material changes in each codebase. I’ve documented all the postgres-specific changes to upstream in the header comment for each file.

I don’t get these compiler warnings and I can’t find any settings to use that might generate them. I’m compiling on macOS 11.6 configured with `--enable-cassert --enable-depend --enable-debug CFLAGS=-O0`
I’ve optimistically updated the patch to hopefully address them, but I’d like to know what I need to do to get those warnings.
