Hi!

Thank you.
 
set jit to off 
 
makes select fast.
I have encountered this issue only in this query in one database
 
There is  variation of this query running with diferent data in different database in same Debian 10 server. It works fast.
Should I disable jit only for this query or in postgresql.conf permanently?
