Panic in CheckNamedValue() for an INSERT prepared statement which receives a nil value

[mihaitodor]

Try running the following code with trino-go-client v0.312.0:

package main

import (
        "context"
        "database/sql"
        "log"

        _ "github.com/trinodb/trino-go-client/trino"
)

func main() {
        db, err := sql.Open("trino", "http://localhost:666")
        if err != nil {
                log.Fatal(err)
        }
        if _, err := db.ExecContext(context.Background(), "INSERT INTO TEST (FOO) VALUES (?)", nil); err != nil {
                log.Fatal(err)
        }
}

You'll observe the following panic:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x98 pc=0x12a2659]
