But for now I suggest that the default prefix on Windows is C:\Program Files\PostgreSQL
More properly: %ProgramFiles%\PostgreSQL
Another suggestion: %ProgramFiles%\PGDG\PostgreSQL (or even %ProgramFiles%\PGDG\PostgreSQL 7.5). Apache2 uses %ProgramFiles%\Apache Group\Apache2.
Note: Many software uses the %ProgramFiles%\<VendorName>\<ProductName> convention, but apparently Microsoft itself puts stuffs right under %ProgramFiles% (%ProgramFiles%\Microsoft Money, \Internet Explorer, \Windows Media Player, etc).
And then, if they don't like that, let them put it wherever they darn well please.
