I know of bot SQL*Server and Oracle database systems on Win32 with hundreds of millions of rows and many hundreds of gigabytes of space. These are production systems, run by fortune 500 companies. I expect that PostgreSQL systems on Win32 will have multiple 64-bit CPU systems, with 16 gigs or so of ram, and a terabyte of disk, not long after 7.5 is released (unless problems with PostgreSQL on that platform turn up). Is that what you have in mind when you say "small systems"? I expect that one year after release, there will be ten times as many PostgreSQL systems on Win32 as all combined versions now on UNIX flavors (of course, that is a SWAG, but I think a sound one)

I surely hope not. Especially not multi-gig databases. The folks
running those should know better than to use Windows, and if they
do not, I'll be happy to tell them so.

Deciding on the platform before examining the app's requirements is always a bad idea, but that's what happens. Respecting this, suggesting "don't use win32 for high performance pgsql databasing" is equivalent to "don't use pgsql". Regards, Andreas

This is a prejudice that we should try to avoid. Yes, Windows is lacking on so many levels, but that really isn't the point. A good box running Win2K or XP Server, with no internet connectivity, and no user applications, can really perform and be reliable. Would I choose this? Hell no, but there are HUGE amount of people who either don't know any better or have no real choice. The REAL bonus here is getting PostgreSQL in their hands. Right now, for the small to medium business running Windows, Microsoft has a virtual lock with SQL Server. SQL Server is expensive and a real PAIN. Giving Windows users PostgreSQL with a good set of .NET, ODBC, and JDBC drivers loosens the Microsoft stranglehold, just a little bit. If they develop their application with MSSQL, there is a good chance it will never use any open source software and always run on Windows. If they develop their application using PostgreSQL, there is a better likelyhood that other open source projects will be used, AND that should the requirement be to upgrade the system, a wider range of OS and hardware options will present themselves.
