What do you want to change?

https://docs.sqlc.dev/en/stable/howto/named_parameters.html

Not working for postgresql. original:

...
when 'all' = $1::varchar then true
...

OFFSET $2::int LIMIT $3::int;

tried both ways in docs :

sqlc.arg(exchange) and @exchange

but get errors: queries/queries.sql:1:1: could not determine data type of parameter $1

WHY bother? Because its annoying/unclear to have to use the following in the code. 

    Column1 string
    Column2 int32
    Column3 int32

What database engines need to be changed?

PostgreSQL

What programming language backends need to be changed?

Go
