The key thing to remember is that Fedora != Red Hat Enterprise Linux. It will have different versions of things installed by default than RHEL, and occasionally won't be compatible with binaries designed for RHEL. Even though both come out of Red Hat.

RHEL tends to stick to old, known versions of libraries and so on. Fedora tends to have newer versions. RHEL always takes the "safe, stable" choice of what versions and packages to bundle. Fedora sometimes tries the new-and-improved options.

Because it is slow to change, RHEL is the deployment standard for all kinds of (binary, sometimes proprietary (read, Oracle)) software. Centos is an unbranded version of RHEL. So if you make a binary on Centos, it should deploy on RHEL, no problem.

With regard to compiling and using PostgreSQL and PostGIS from source on Fedora or RHEL or Centos, it should not make any difference at all. The only reason to get your knickers in a knot about distros is if you know you are going to have to provide binary packages to a client that will work on their systems, because if they are a large organization using Linux, there is a very high probability it will be RHEL.

 Can you briefly explain how Centos differs from Fedora when it comes
to using PostgreSql and PostGis?

Check with EnterpriseDB, they are the only ones I can imagine both
with binaries for oddball architectures.

Is Itanium II
really such a rare/boutique platform as ESRI seems to
believe it to be by not supporting it fully?

Yes, yes it is. I wouldn't spend any money on it, myself, until it
proves itself in the market (and it has had a lot of time to do so,
with little avail thus far). It might be great, but so was the DEC
Alpha.

P.S. What's the "best" Enterpise class Linux for
PostGIS/PostgreSQL? I hear Centos and WhiteHat are
RedHat Enterprise without the logos.

Centos I have heard of. WhiteHat I have not. Yes, that is what they are.

What Enterprise Linux do people here use for
PostGIS/PostgreSQL (for personal work where there is
little to no funding)?

Centos.
