> This query should return 1,2,3,4 in both columns but returns null in the second column. Both tables are in a Postgres 9.5 server mapped under Drill
> select tint.rnum, tbint.rnum from postgres.public.tint , postgres.public.tbint where tint.cint = tbint.cbint
> create table TINT ( RNUM integer  not null , CINT integer   ) ;
> insert into TINT(RNUM, CINT) values ( 0, NULL);
> insert into TINT(RNUM, CINT) values ( 1, -1);
> insert into TINT(RNUM, CINT) values ( 2, 0);
> insert into TINT(RNUM, CINT) values ( 3, 1);
> insert into TINT(RNUM, CINT) values ( 4, 10);
> create table TBINT ( RNUM integer  not null , CBINT bigint   ) ;
> insert into TBINT(RNUM, CBINT) values ( 0, NULL);
> insert into TBINT(RNUM, CBINT) values ( 1, -1);
> insert into TBINT(RNUM, CBINT) values ( 2, 0);
> insert into TBINT(RNUM, CBINT) values ( 3, 1);
> insert into TBINT(RNUM, CBINT) values ( 4, 10);
