Does Win32 do symlinks these days? I know Win32 does envvars, and Win32
is currently a supported platform.
I'm not thrilled with either solution -- envvars have their problems
just as surely as symlinks do.

FWIW, count me here. I have tried administering my system using the
filenames -- and have been bitten. Better admin tools in the PostgreSQL
package beat using standard filesystem tools -- the PostgreSQL tools can
be WAL-aware, transaction-aware, and can provide consistent results.
Filesystem tools never will be able to provide consistent results for a
database system that must remain up 24x7, as many if not most PostgreSQL
installations must.

Sorry Bruce -- I understand and am sympathetic to your position, and, at
one time, I agreed with it. But not any more.
