Fix database creation with Postgres

* Database.py : fillDefaultData()

PostgreSQL has a rather annoying (mis)feature when dealing with boolean
data types: raw 1/0 input as integer is not automatically cast to
boolean values. Instead, one must use one of several other ways of
signifying true/false.
http://www.postgresql.org/docs/8.4/static/datatype-boolean.html
documents the available and understood formatting.

Fix by special-casing PostgreSQL and making all boolean values fed as
strings, '1' for true and '0' for false.
