There is a _HUGE_ set of misconceptions here.
1. The speed difference is only repeatedly true for simple selects
when done against MyISAM tables.
2. That speed difference for UPDATEs is only true if you are talking
about ONE MySQL(tm) client doing updates against MyISAM tables.
MyISAM does not support row locks; if multiple clients are
trying to update a table, they must fight for a single table
lock, with the result that updating tables doesn't scale _at
all_ with MySQL(tm) for the default table type.
If you only have one process touching the database, MySQL(tm) can
therefore look quite a lot better than PostgreSQL. Move to 2 clients
and it's not quite so good. Move to 100 concurrent clients all trying
to do updates and you may discover that you simply can't do that...
