[development] Fundamental MySQL changes in Drupal 6 (six)

[Karoly Negyesi]

Just to record my research.

> GROUP_CONCAT Again, not standard and the only solution for pgsql I know requires plpgsql

a) sammys has no probs with plpgsql
b) while many routines require plpgsql from http://pgfoundry.org/projects/mysqlcompat/ but group_concat does not. Yay.

So, in case we need it, I think it's good to go, I provided Oracle and pgsql implementations -- but again, this will need further discussion when there will be an issue that's best solved with GROUP_CONCAT.
