For us?
Stability. Pure and simple. It ended up that the site was faster too.
One issue with postgresql is that connection time is slower than
mysql. Otherwise most everything else is just as fast or faster.
So with Ruby on Rails, there is a persistent connections from the
container, and that disadvantage dissapears. If there's anything slow
in the site, its ruby template rendering, database access generally is
10% or less of total time it takes to generate our most popular pages.

Rdb/VMS and CODASYL DBMS (both Oracle, formerly DEC, products) also
have transactional DDL. Actually, I was quite stunned to discover
that Oracle doesn't do that.
Interbase/Firebird probably also has transactional DDL.
