Why is db_postgres so slow?

[Polarian]

You are free to write a postgres client fully in nim, the protocol is open, its 
probably a lot easier to have a full nim varient, instead of wrapping a 
library. It means you have more control instead of just adding nim bindings to 
a library, and you can design the infrastructure yourself (for example to make 
it fully async based, which will help with the blocking problem)
