Hi
I am testing new features in Postgres 14, and I found bug
EXPLAIN ANALYZE VERBOSE for insert to FDW table with batch_size 1000
returns
-------------------------------------------------------------------------------------------------------------------------------
Insert on public.vzdalena_tabulka2 (cost=0.00..175.00 rows=0 width=0)
(actual time=30.269..30.270 rows=0 loops=1)
Remote SQL:
\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F\x7F
Batch Size: 1000
-> Function Scan on pg_catalog.generate_series g (cost=0.00..175.00
rows=10000 width=36) (actual time=0.453..1.988 rows=10
Output: g.i, ('AHOJ'::text || (g.i)::text)
Function Call: generate_series(1, 10000)
Planning Time: 0.075 ms
Execution Time: 31.032 ms
