Thanks Markus.

enough. There seem to be two ideas floating around:

When I submitted the proposal, AFAIR there was no objection to going with
the first proposal. Yes there was a lot of forward looking discussion, but
since what I had proposed (atleast syntax wise) was similar/closer to Mysql,
Oracle I did not see any one objecting to it. I think SQL server provides
partitioning functions similar to Simon's proposal. And all along, I had
maintained that I wanted to automate as far as possible, the existing
mechanism for partitioning. To this too, I do not remember anyone objecting
to.

Our current partitioning solution is based on inheritance. With that in
mind, for 8.3 I thought an implementation based on auto rules creation would
be the way to go.

Having said that, obviously I would want to go with the consensus on this
list as to what we think is the *best* way to go forward with partitioning.

Nikhils
