I love Postgres, but the only thing I find myself wishing for was better Unicode support in the regex engine. I like to add strong database constraints, and sometimes lean on the regexp engine but I find it's missing a lot of features available in other regexp engines. PCRE compatibility would be ideal, but even just support for the Unicode \p classes would be a big step up.
