Price difference seems huge. Looks more than Oracle? Can anyone explain why?

Either they updated the table since you posted, or you're misreading it. MySQL Large is $0.32/hr, PG Large is $0.336/hr, Oracle is $0.565/hr.

I don't know why the MySQL/PG prices are different.

My fault. I misread it. PostgreSQL has only heavy-utilization unit on reserved instance. I thought it's light utilization unit.

Heavy/Large/1yr(reserved, multiAZ)/Tokyo: PostgreSQL = $1548, Oracle = $2440

Seems reasonable price. And I don't care MySQL price because it's not an option to me.
