Hi,
I tried the following on the upgraded database:
analyze schema_test.table_a;
But the result is the same.

"Sort (cost=5.94..6.01 rows=26 width=6) (actual time=0.199..0.200 rows=3
loops=1)"
" Sort Key: table_a.col0002"
" Sort Method: quicksort Memory: 2
Hi,
Thank you very much for your answers.
Yes, 50 rows aren't enough, but the original table has about 14 million rows
and after analyzing the table I got the same result.
We changed our functions and used string_to_array instead of unnest and its ok.
It was not only a problem with one value
