Error: There are 2 missing dependency paths.
2 targets had depfile dependencies on 1 distinct generated inputs (from 1 rules) without a non-depfile dep path to the generator.
There might be build flakiness if any of the targets listed above are built alone, or not late enough, in a clean output directory.

I think it's not right that something in src/port defines an SQL callable
function. The set of headers for that pull in a lot of things.

Since the file relies on things like GUCs, I suspect this should be in
src/backend/port or such instead.
