The following bug has been logged online:
Bug reference: 3681
Logged by: ITAGAKI Takahiro
Email address: itagaki(dot)takahiro(at)oss(dot)ntt(dot)co(dot)jp
PostgreSQL version: 8.2.5, 8.3beta1
Operating system: independent
Description: fillers are NULL in pgbench
Details:
All of filler fields in branches, tellers and history is NULL. It is
probabbly a mistake because there are fields of char(22-88) in the table
definitions.
TPC-B requires at least 100 bytes per row for all tables used in it.

I'm not in favor of changing this. pgbench has never pretended to be
"really" TPC-B, nor has anyone ever tried to compare its numbers against
other TPC-B numbers. On the other hand, people *do* compare pgbench
numbers to itself over time, and if we make a change like this it will
break comparability of the results.
