Sorry, no, that was not the intent at all. I just meant to let you know that there was no 64 bit version of PostgreSQL on Windows that we could use, thus we could not build a 64 bit Windows version of ArcSDE for PostgreSQL, that's all. The other technical details provided in that thread may be interesting, but are really just extra info you probably didn't need.

In January, we started building a version of ArcSDE 10 for PostgreSQL on Red Hat Enterprise Linux 5 update 4. This is a 64 bit implementation. Our goal is to fully test and certify this as ready to ship with pre-release in March.
