Обсуждение: uniqueidentifier datatype for 7.3.X

Hi All!

I've ported uniqueidentifier datatype to upcoming PostgreSQL 7.3. It's
available at
http://www.taurussoft.org/files/uniqueidentifier-0.1.9.3.tar.gz
In this release there is additional function uniqueidentifier_text()
which converts uniqueidentifier to text datatype. Thanks to Hussein
Patni!

Version for 7.2.X is available at
http://www.taurussoft.org/files/uniqueidentifier-0.1.9.2.tar.gz
Version for 7.1.X is available at
http://www.taurussoft.org/files/uniqueidentifier-0.1.9.1.tar.gz
The only difference between two releases is adoptation to 7.2.X system
catalog. No new functions/bugfixes.

Uniqueidentifier datatype is 128-bit (16 byte) wide datatype claims to
be unique across Universe. It's a good choice for primary indexes and
making relations between tables.
This inplementation depends on libuuid library from e2fsprogs package by
Theodore Ts'o.

You would be better off to name the conversion function text(uuid)
and declare it as a cast (possibly an explicit-only cast, depending on
whether you think automatic casting of uuid to text is a good idea).
Not following the standard naming convention for conversion functions
just creates an extra memory burden for users.

Thanks, Tom. I thought about it but I should consult with doc how to do
so. Now I simply add Hussein's function to the package because my task
was to port datatype itself.
