S01E01 Why ?

• Why golang sql and sqlx libraries can't parse array_agg ?

• Why golang json library parse [null] as a struct with default values (int = 0, string = "") instead of an error or an empty array ?

• Why postgres COALESCE(jsonb_agg(DISTINCT to_jsonb(ti)), '[]') still returns [null] instead of [] ?
  I want to add FILTER…
