Any links / extra info you want to share? I'd be very interested in seeing my own shortcomings here.

People have a tough time thinking in sets. This applies to developers as well. This is why people constantly fight the relational paradigm; you end up with things like CouchDB or OODBs because they make more sense to developers. It's easier to reason about an object than it is about a set of data.
I've been working on writing a bunch of "SQL from the ground up" postings, but I keep getting side-tracked with another project I'm working on and I haven't had a blog in years to post it on. Besides that, 99% of all the SQL work I've done has been in Sybase, MS-SQL and Oracle; so I'm not sure how relevant T-SQL & PL/SQL are to MySQL or Postgres. I'm assuming the basics are all the same though (which is to say ANSI compliant).
I've worked with both, they both have their learning curve, whatever you already know is going to be 'easier' to you because you don't have to unlearn any habits, I wouldn't advice anybody to use either until I know more of the intended application.
