In our UI case, we already have a queue. Because libpq can't pipeline
multiple queries, we have to make our own queue of them anyway.
In libpqxx (the C++ API) you do get support for this kind of pipelining.
Look for the "pipeline" class. It uses the "concatenate queries,
retrieve multiple results" trick.
The pipeline also serves as an easy-to-manage interface for asynchronous
querying: fire off your query, go do other things while the server is
working, then ask for the result (at which point you'll block if necessary).
