I doubt we are going to change Postgres to improve Drupal support --- it
would be better to fix Drupal.

However, I have a few suggestions:

For this item, http://drupal.org/node/555580, use || for concatentation.

I can't believe MySQL doesn't support multi-column indexes,
http://drupal.org/node/555558.

For this item, I think you want DELETE FROM history USING ...,
http://drupal.org/node/555562.

The SQL standard doesn't support multiple deletes, so odds are we will
not either, http://drupal.org/node/555648.

I show multi-value INSERT was added in PG 8.2, not 8.4, * Add
support for multiple-row VALUES clauses, per SQL standard (Joe, Tom),
http://drupal.org/node/555568.

I am confused because I thought Drupal worked with Postgres, but looking
at your list, it seems it doesn't.
