Hmm, I know NT's not really a target, supported OS, but enshrining
symlinks in a the design of a backend feature makes it really difficult
to keep even the semblance of support. Vadim's work _finally_ stomped
the mixed case tablename bug ("Test" and "test" would collide because of
NTFSi being case insensitive). Symlinks are, I think, only supported via
a Cygwin kludge.
'Course, one could argue that running pgsql via Cygwin is all a big
kludge. I'm not even sure why I keep coming to the defense of the NT
port: I'm not using it myself. I keep getting the feeling that there's a
real opportunity there: get pgsql onto developer's NT boxes, when their
projects need a real database, rather than springing for an MS-SQL or
Oracle license. Makes moving over to a _real_ operating system (when
they start to notice those stability problems) that much easier.
But seriously, there was a long thread concerning the appropriateness
of using symlinks to manage storage, which I don't recall as coming
to a conclusion. Admittedly, the opinion of those who take the bull by
the horns and actually write the code matters more (rough concensus and
working code, as they say).
