This version, being an early Alpha Version, was tested thoroughly
with MySQL as one of the more used Databases.
More comprehensive tests with PostgreSQL and SQLight are not done yet.
The problem with the double quotes for PostreSQL is correct. Seems
also to be a general problem in Symfony too, at least to some extend
in some of the plugins.
If you find a general fix for it, we will test it and take it into
account for the next release of Steer CMS. There will be probably
more database dependencies then that for all the different database
types. Will need to check that out.
For the time being, if possible, you can run Steer CMS with MySQL.
