Why the size (PQ_BUFFER_SIZE) of backend send buffers is 8192 ? Can i set it
to other value ?
If i extend or decrease it , can it affect the performance of sending message?

In principle, it is just an arbitrary amount by which to increase the
I/O buffer size. Of course it has to

Traditionally, at least, that was the size of pipe buffers in Unix
machines, so in principle this is the most optimal chunk size for
sending data across a Unix socket. I have no idea though

Well, you could try PMTU discovery, though I agree that it's not
great. It also seems pretty low-level for something like the DBMS to
be doing.
