MySQL copyfrom with query_parameter_limit: 0 generates invalid go code

[Gardego5]

Version

1.26.0

What happened?

When generating a copyfrom query in mysql and setting the query_parameter_limit to 0, sqlc incorrectly generates an invalid go file, calling the (e *mysqltsv.Encoder).AppendString(s string) function with an array of structs as the argument. This code does not compile.

Relevant log output

No response

Database schema

CREATE TABLE author (
  id   BIGINT UNSIGNED PRIMARY KEY,
  name text            NOT NULL
);

SQL queries

-- name: CreateAuthors :copyfrom
INSERT INTO author
	(name)
VALUES (?);
