First of all - thank you for this extremely useful tool!

Sqlc uses int32 type as parameter for LIMIT in queries, for example for this query

-- name: ListAuthors :many
SELECT * FROM authors
ORDER BY name
LIMIT $1 OFFSET $2;

sqlc will generate this set of params:

type ListAuthorsParams struct {
	Limit  int32
	Offset int32
}

According to Postgres docs it should be also possible to use NULL as the argument to LIMIT to effectively omit the LIMIT clause. This is very useful for queries where LIMIT is optional.

It's possible to work around this by passing some arbitrary large number as the parameter, but that seems like a hack.

Would it be possible to use something like sql.NullInt32 instead of int32 as the parameter for LIMIT so that it's possible to dynamically assign NULL to LIMIT in queries?
