Hello there
I am trying to play around with the hashjoin algorithm in postgres.
I am using the statement like
Select count(*) from r,s where r.id=s.id;
I looked at the function ExecHashJoin() in nodeHashjoin.c and cannot
find where the algorithm is comparing if r.id equals s.id
please advise
from my understanding, postgres first needs to partition the tables.
ExecHashTableCreate() is the function that partitions the tables right?
