Decoding error when calling a function that returns void

[fancycade]

I made a function to do a complex update so I had no need for a return value, hence the void return type.

My use of pgo looked like this:

pgo:query(<<"SELECT foo($1)">>, [Id])

This resulted in pgo erroring out not knowing how to decode the value which is understandable.

The easy workaround was to set the return type to integer, and return 0 in the function.

I'm not sure if this really needs to be fixed, but I thought it was worth reporting the error since it failed on a valid postgres query.

Can you cast to void, like pgo:query(<<"SELECT foo($1)::void">>, [Id])?
