I've noticed that if a client uses PQexecParams, the query plan
appears to be identical to the plan chosen for PQprepare/PQexecPrepared,
which might not be as optimal as a plan chosen for PQexec. I can
understand the PQprepare case since the planner doesn't know what
parameters will actually be used, but with PQexecParams shouldn't
the planner have all the information it needs to choose a plan based
on specific parameters? Is PQexecParams just shorthand for a prepare
followed by an execute?
