Expected behavior of :one query annotation in case of multiple rows return

[rmodpur]

I'm using sqlc with pgx/v5 in go, for a delete query with :one annotation for eg.

-- name: DeleteEmployee :one
delete
from employee
where employee_id = $1
returning employee_name;

I was expecting it to fail withpgx.ErrTooManyRows if the query returns more than one row but what i found was it picks the first row and just ignores the rest. sqlc codegen for pgx uses QueryRow method of pgx which has the behavior of ignoring all the rows but one if there are multiple, would it be possible to use Query along with CollectExactlyOneRow in place of QueryRow(jackc/pgx#1411 (comment)) ?
