Contract
- assert RowToStructByName fails when scanning NULL into plain Go scalar type
- assert RowToStructByName succeeds with nil for *T and Valid=false for pgtype types on NULL
- assert RowToStructByName fails on missing columns, while RowToStructByNameLax allows missing columns in row
- assert RowToStructByNameLax fails when row contains extra columns not in struct
- assert RowToStructByPos ignores fields tagged with db:"-"
- assert pgxpool.Conn panics on Conn() or Exec() after Release(), but multiple Release() calls do not panic
