`query_parameter_limit` breaks `batchexec` queries

[SoMuchForSubtlety]

Version

1.25.0

What happened?

If the number of parameters for a batchexec is ≤ query_parameter_limit, the struct for the parameters does not get generated.

The generated function still tries to use the missing struct, and thus does not compile.

Relevant log output

No response

Database schema

CREATE TABLE authors (
  name text      NOT NULL,
  bio  text
);

SQL queries

-- name: CreateAuthors :batchexec
INSERT INTO authors (
  name, bio
) VALUES (
  $1, $2
);

Configuration

{
  "version": "2",
  "sql": [{
    "schema": "schema.sql",
    "queries": "query.sql",
    "engine": "postgresql",
    "gen": {
      "go": {

        "sql_package": "pgx/v5",
        "query_parameter_limit": 2
      }

  }]
}

Hi @kyleconroy

It seems there is another bug with the batchexec. It's visible in the linked playground in the description. The generated batch.go file imports "github.com/jackc/pgx/v5/pgtype" which is never referenced, which causes a compilation error
