A month has passed without a response, I close.

@negezor thank you for the issue! Do you want to create PR?)

@tyt2y3 @billy1624 Well, shall we add or is it too specific for postgres?

Hello! I created PR: https://github.com/SeaQL/sea-query/pull/473

@billy1624 @tyt2y3 , hello! I have a bad surprise. `trait ToSql` from `postgres-types` crate need: `Self: Sized`, but I cannot make `ValueTrait: Sized`, because I need `dyn ValueTrait`

It looks like instead of create our own `ValueTrait` make all types, which hold `Value` should be generic...

Hmmm another sought... Black magic with unsafe. This should work. I can store row pointer to data and then transmute it to value and type get from enum. Example: https://github.com/Diggsey/ijson/

Ah, one more problem... I try something like this: ```rust pub trait Sqlx + Type {} pub trait ValueTrait where Self: Debug, { fn to_sql_string(&self) -> String; #[cfg(feature = "with-postgres")]...
