Does anyone knows if removing the field names from an INSERT query results in some performance improvements?

I mean is this:

INSERT INTO table1 VALUES (value1, value2, ...)

faster for DB to be accomplished rather than doing this:

INSERT INTO table1 (field1, field2, ...) VALUES (value1, value2, ...)

?

I know it might be probably a meaningless performance difference, but just to know.

I'm usually using MySQL and PostgreSQL as DBs.
