So you think the DBA can do partitioning? Good.
Setting up partitioning in Oracle or SQLServer2005 requires lots of
syntax and multiple commands. There are fewer commands with PostgreSQL
and they are ISO/ANSI compliant also.
I think there is much still left to do with partitioning, so I would be
the first to say that this is only the beginning. I know you are wary of
overstating capabilities; so am I, but it looks like we differ slightly
on where to draw the line.
On reflection, the only changes I suggest are:
1) the phrase "This allows for a type of table partitioning" have the
word "basic" inserted within it to become: "This allows for a basic type
of table partitioning"
2) placing CE as a major feature of 8.1 - many people regard it at least
as highly as other optimizations, though this is subjective based upon
their application requirements
Suggestion (2) might be seen as some kind of vanity, so having raised
the issue I'll leave the floor open to others to agree or not.
