Re: Patch: initdb: "'" for QUOTE_PATH (non-windows)

I looked into this and soon found that fe_utils/string_utils.o has
dependencies on libpq that are much wider than just pqexpbuffer :-(.
It might be a project to think about sorting that out sometime, but it
looks like it would be an awful lot of work just to avoid having initdb
depend on libpq.so.  So I now think this objection is impractical.
I'll just annotate the makefile entry to say that initdb itself doesn't
use libpq.

I still think this is worth fixing, but it's a simple modification.
Will take care of it.

This item is listed in the commitfest as a bug fix, but given the lack of
previous complaints, and the fact that the printed command isn't really
meant to be blindly copied-and-pasted anyway (you're at least meant to
replace "logfile" with something), I do not think it needs back-patching.
