failed to do direct dispatch when filtering gp_segment_id on conjunction/disjunction constraints setup : #create table foo (a int); #explain select * from foo where gp_segment_id=0 and a between 1 and 10; Sol: -- This PR filterts the gp_segment_id on constraints with conjunction/disjunction -- Tries to do direct dispatch if finds gp_segment_id in constraint. ---
