You might try seeing whether:
FROM table1 JOIN (
SELECT field7, array_agg(row(f1, f2)) AS values_array FROM table2 GROUP BY
field7
) tbl2_agg USING (field7)
helps...
I'm also dubious (though this isn't necessarily a performance issue) of:
array[...] AS metadata
Without context I would say this would be better as a composite type instead
of an array. You may find it useful to use named composite types elsewhere
too...
