 * @param Sql|string $query SQL query to execute (must have ORDER BY matching keyset columns)
 * @param KeySet $keySet Columns to use for keyset pagination
 * @param list<mixed> $parameters Values bound by position to $1, $2, ... placeholders; wrap with {@see \Flow\PostgreSql\DSL\typed()} to force a specific PostgreSQL type
