Hello,

pgbench mixes int and int64 to initialize the tables.
When a large enough scale factor is passed, initPopulateTable
overflows leading to it never completing, ie.

2147400000 of 2200000000 tuples (97%) of
pgbench_accounts done (elapsed 4038.83 s, remaining 98.93 s)
-2147400000 of 2200000000 tuples (-97%) of
pgbench_accounts done (elapsed 4038.97 s, remaining -8176.86 s)

Attached is a patch that fixes this, pgbench -i -s 22000 works now.
