Is is standalone query.
This is exact statement executed in PgAdmin window and exact result copied
from pgadmin result windw.

I tried it again and got

"Seq Scan on dok  (cost=0.00..186943.67 rows=5974 width=1173) (actual
time=39275.713..39319.865 rows=1 loops=1)"
"  Filter: ((dokumnr)::double precision = 1228137::double precision)"
"Total runtime: 39320.030 ms"
