Re: Support run-time partition pruning for hash join - Mailing list pgsql-hackers

Please look at a warning and an assertion failure triggered by the
following script:
set parallel_setup_cost = 0;
set parallel_tuple_cost = 0;
set min_parallel_table_scan_size = '1kB';

create table t1 (i int) partition by range (i);
create table t1_1 partition of t1 for values from (1) to (2);
create table t1_2 partition of t1 for values from (2) to (3);
insert into t1 values (1), (2);

create table t2(i int);
insert into t2 values (1), (2);
analyze t1, t2;

select * from t1 right join t2 on t1.i = t2.i;
