Support of schemas and tablespaces in Drupal 4.6

Since there are now 'real' RDBMS out there are

a) GPLed
b) quite easily installed (on Windows as well as on Unix)
c) support tablespaces and schemas

What about a postgresql installer for 4.6 that would allow a user to configure the parameters about where the tables and indexes go tablespace-wise, and which schema to use? Maybe some sort of perl or PHP script that could simply configure the .pgsql file in such a way, and also create the database correctly for those that already use PostgreSQL 8.0.1?
