I have prepared a patch to backends/commands/async,c to speed up
duplicate elimination. rdtsc timing results are sent back via ereport.

I didn't remove the the original list code.
The tree
I know that it is not a big problem for most users, but allowing a very

{
char *channel ;
char *payload ;
uint32 hash ;
struct
