from my understanding, postgres first needs to partition the tables.
ExecHashTableCreate() is the function that partitions the tables right?

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
