Rows parsing is the central logic that iterates over the result of a query and creates domain values.

This PR tweaks the way this is done by:

  • using values instead of pointers as we are returning slices of small structs
  • allocating only when necessary

Hopefully this will reduce slightly the memory footprint and (more importantly) will reduce the allocation count, reducing pressure on the GC.
