Hello all,

I am a student-magister and I'm writting my magister work. I realized gist

*set enable_seqscan = false
select * from table_of_moving_objects where mov_obj ~ box '(0,0) (1,1)'*

I can not understand why DB is restarting ? It is restarting when SQL begins
use index :(((
Can anybody help me , I would by appretiate every people who downloads my
sources, try to deploy index and maybe solve where is the problem.
