I think that the first argument of [psql] could be a receive-symbol, 
followed by the query itself. Then [psql] would not use the receive-symbol 
to send messages to, it would look at the receiver directly, checking that 
it's a [psql.connection] object, and then calling a function of that 
object directly, and get called back when a response is received. This is 
quite close to how [tabread] works except it inserts a [delay] before the 
result. It's how [tabread] would work if it were trying to access an array 
on another computer.
