[Postgres-xc-developers] Fixing pgbench bug

[坂田 哲夫 <sak...@la...>]

Hi, folks,

I found a pgbench bug that pgbench fails to update tables such as
pgbench_accounts and pgbench_tellers.

For example, original pgbench for XC tries to update pgbench_accounts'
specifying aid and bid values which are selected independently.
By the pgbench's nature, bid should have a particular value for a
given aid value. So the update statement fails picking up target
tuple and updating the table in most cases.

The attached patch, which should be applied to XC 1.1s
pgbench, eliminates wrongly added bid specifications
and corrects index and distribute settings related.

Best regards,

Tetsuo Sakata.
