You said:
"Essentially, this makes win32 impossible in a 24x7 environment (jokes
aside about Win32 in general) because we *have* to defrag on Windows and
Windows won't defrag open files (thus anything PostgreSQL is using)."
What I am asking for is evidence to back up that assertion. At the moment
it is, as Tom likes to say, "a fact not in evidence".
(I should have thought a single file DB would be MORE liable to
fragmentation, BTW).
