I'm complaining specifically about the resolving of symlinks.  Why does

$ /usr/local/opt/postgresql@13/bin/pg_config --bindir

print

/usr/local/Cellar/postgresql@13/13.8/bin

when it clearly should print

/usr/local/opt/postgresql@13/bin

This is unrelated to the support for relocatable installations, AFAICT.
