explain format json, unit for serialize and memory are different.

hi.

explain(analyze, format json, serialize, memory, costs off, Timing
off) select * from tenk1;
QUERY PLAN
---------------------------------
[
{
"Plan": {
"Node Type": "Seq Scan",
"Parallel Aware": false,
"Async Capable": false,
"Relation Name": "tenk1",
"Alias": "tenk1",
"Actual Rows": 10000,
"Actual Loops": 1
},
"Planning": {
"Memory Used": 23432,
"Memory Allocated": 65536
},
"Planning Time": 0.290,
"Triggers": [
],
"Serialization": {
"Output Volume": 1143,
"Format": "text"
},
"Execution Time": 58.814
}
]

explain(analyze, format text, serialize, memory, costs off, Timing
off) select * from tenk1;
QUERY PLAN
---------------------------------------------------
Seq Scan on tenk1 (actual rows=10000 loops=1)
Planning:
Memory: used=23432 bytes allocated=65536 bytes
Planning Time: 0.289 ms
Serialization: output=1143kB format=text
Execution Time: 58.904 ms

under format json, "Output Volume": 1143,
1143 is kiB unit, and is not the same as "Memory Used" or "Memory
Allocated" byte unit.

Do we need to convert it to byte for the non-text format option for EXPLAIN?
