remove Default in migration?

Surprisingly or not, for NOT NULL fields ->default(null) removes the default from a table:

public function up()
{
    Schema::table('client', function (Blueprint $table) {
        $table->boolean('enabled')->default(null)->change();
    });
}

Just omitting the default() part doesn’t work, since laravel makes a diff between current state and current state + specified changes. No changes specified, no diff.

After that, doctrine generates ALTER TABLE statement, treating NULL as no default value.

With nullable fields though, from what I can see, doctrine doesn’t let you simply drop the default. The only option is supposedly to make them NOT NULL:

public function up()
{
    Schema::table('client', function (Blueprint $table) {
        $table->boolean('enabled')->nullable(false)->default(null)->change();
    });
}

Maybe with PostgreSQL you can get away without converting to NOT NULL, but that’s to be confirmed.
