Hi,

More and more lately it feels the need to have an aproximate (phonetic) search 
on character fields.

In fact it is a common feature nowadays (thanks, Google) and the users want to 
see it also in their applications.

PostgreSQL has it (see this for a neat implementation)

http://www.postgresql.org/docs/current/static/fuzzystrmatch.html

MSSQL has it (see this for neat conversion from C++ to T-SQL)

http://www.sqlmag.com/article/tsql3/double-metaphone-sounds-great-26094

MySQL has it (see this for a neat discussion)

http://stackoverflow.com/questions/369755/how-do-i-do-a-fuzzy-match-of-company-names-in-mysql-with-php-for-auto-complete

Like the other Databases said, I would propose a Double Metaphone 
implementation in FB 3.0

For Double Metaphone see in the middle of the Wikipedia Metaphone page:
