I saw this original article via LinkedIn and a conversation ensued on Google+ and I thought some of the comments were worth posting here.

The question was raised, that because PostgreSQL was an old SQL model, wont it have the same problems as MySQL and Wes Devauld (of BeefyApps fame) commented stating:

Wes Devauld: Postgres was built from the ground up using MVCC, which has a much smaller overhead in update transactions. MySQL InnoDB 5.1 added MVCC, but I’ve read that the implementation is half assed and they are still hamstrung on how they handle the transaction logs.

I thought it was a comment worth preserving, for posterity.
