thinkphp在PostgreSQL下兼容ON CONFLICT DO NOTHING处理方法
由于thinkphp只对Mysql有INSERT IGNORE方法，PostgreSQL是ON CONFLICT DO NOTHING方法，但是thinkphp orm一直没有支持，只能暂时在model用这个方法.
public static function insertIgnore(array $data, string $conflictTarget = null): int
{
$rawSql = static::fetchSql(true)->insert($data);
if ($conflictTarget) {
$rawSql = "{$rawSql} ON CONFLICT {$conflictTarget} DO NOTHING";
}
return Db::execute($rawSql);
}
none
