The discussion thread seems to start here:
http://archives.postgresql.org/pgsql-hackers/2002-08/msg00306.php
As best I can tell the objections came from the fact that Thomas had
implemented it as a postmaster-start-time switch, which made it a
foot-gun because you could mistakenly start the postmaster with a
different XLOG than you were using before. That would not apply to a
symlink-made-by-initdb approach. All this is doing is formalizing
something we already suggest people do by hand...
