[support] Drupal 7 and postgres opinions

Hi, I'm looking at bringing up a new multi-site under postgres for a set of D7 sites. I'm wondering if people have opinions on whether there are performance gains in using postgres and any other feedback about performance and ease of use with the new abstract interface. These sites will have ubercart, but are primarily brochure sites with multiple authors.

From what i've seen, until the site is thoroughly cached D7 runs a bit slow under mysql. I'm also hearing stories of the database getting corrupted, though i think that's probably from not having enough memory set in php.ini.

Thanks. -Don-
