It's generally a lot better (faster, cleaner, clearer) to do this type of stuff in the database. All you need is an aggregate function that concatenates strings with a space delimiter. Here are several ways to do it for PostgreSQL, SQL Server, and MySQL:

With Postgres and DBD::Pg you can get an actual array instead of a delimited string.
