This is because PostgreSQL installs its Makefile(!), which contain
absolute references to various build tools.

I pushed a fix to 'staging' in
e693617f559f49d1d2606dd5ad997e444b9ad1b5 that adjusts the Makefile to
use relative references.

(not sure whether it should be installed at all, but that is for a
future bug report)

The size of postgresql@13 decreased from 256.3 MiB to 137.9 MiB(!!).

Thanks!
