Implemented CQRS+ES design pattern recently in F# and postgres. The query side kept changing due to business needs, while the command side remained the same.
In our case, queries state aka projection were asynchronous which made it very flexible and fast to work with. Projection could live anywhere, within the web server, redis or just database.
