Feedback about Drupal SQL debugging

Dear friends,

I have been using PostgreSQL since 6.3 releases and I am a real fan.
Of course, I never use nor trust MySQL to deliver data.

Now I use Drupal 6.3 with PostgreSQL 8.4.

I loose a lot of time correcting Drupal SQL.
You may be interested in my developer feedback.

I gathered some real examples here: Guidelines for writing MySQL and
PostgreSQL compliant SQL => http://drupal.org/node/555514

This page gathers most frequent problems that Drupal users and
developers encounter when using PostgreSQL.

I would be delighted to have your feedback.
Could some issues reasonably be fixed for a better Drupal support?

Kind regards,
Jean-Michel
