Indeed, because I just wanted to reimplement *how* we resolve the
executable path to absolute, not question whether we should do it at all.
Well, if we decided not to do it, then we could just delete the code and
not have to think about how to change it.
I'm not familiar with how homebrew sets up the installation
layout, but I'm suspicious that the situation Peter refers to
has a similar problem, only with a symlink for the bin directory
not the individual executable.
I think the two contradicting use cases are:
1) You configure and install with prefix=/usr/local/pgsql, and then
symlink ~/bin/pg_ctl -> /usr/local/pgsql/bin/pg_ctl; hoping that that
will allow pg_ctl to find the other programs it needs in
/usr/local/pgsql/bin. This is what we currently support.
2) You configure and install with prefix=/usr/local/pgsql-14, and then
symlink /usr/local/pgsql -> /usr/local/pgsql-14; hoping that you can
then use /usr/local/pgsql as if that's where it actually is. We don't
currently support that. (Note that it would work if you made a copy of
the tree instead of using the symlink.)
I don't know if anyone uses #1 or what the details of such use are.
#2 is how Homebrew and some other packaging systems work.
