I disagree; all of these databases have distinctly different uses.

MySQL/PostgreSQL: pick your poison. Relational databases. Will you have  
multiple users connecting to the database? Will there be lots of updates  
to the data? These are what you want. If you care about data integrity,  
I'd choose Postgres.

SQLite: Do you want a relational database without needing a daemon to be  
running and will only have a single user/process accessing the database at  
one time? This is what you want.

NoSQL: Do you want to dabble with the mess that is NoSQL so you can build  
your "cloud"? Don't care if other nodes aren't guaranteed to get the  
latest copy of the data? This is what you want.

SleepyCat/BerkleyDB: Is your data WORM? (Write Once Read Many) If so, this  
is *ABSOLUTELY* what you want.

If twitter was built upon a WORM database instead of MySQL they could host  
the entirety of twitter on a handful of servers instead of the gross  
MySQL+Cassandra mess they're fighting with today.
