Why do we do this? What compatibility reasons?

It's been a while since I dealt with any of our pg stuff at work, but I think Postgres doesn't actually allow you to drop columns... You would have to create a new table without the column, and then move all the data over.

Could be completely off-base though!

Postgres 7.4 and 8.0 can both drop a column. ..chrisxj
