When executing "SELECT * FROM pg_stat_activity" I get lots of rows that
have an empty "query" column.
According to [1] this column should contain the "Text of this backend's
most recent query", either a query that is currently running or the last
query that was executed.
So how comes that a lot of the rows in pg_stat_activity have an empty
"query"?

They've never executed a query. Probably due to connection pooling opening connections for the pool but never needing to hand them out.
