Various pgbench enhancements. Patch contributed by ITAGAKI Takahiro.
Also tweak README.pgbench/README.pgbench_jis: Remove history after pgbench was added to PostgreSQL contrib module. Those info was not only redundant since it has already been in CVS log, but also incomplete. -------------------------------------------------------------------------- The attached is a patch to optimize contrib/pgbench using new 8.3 features. - Use DROP IF EXISTS to suppress errors for initial loadings. - Use a combination of TRUNCATE and COPY to reduce WAL on creating the accounts table. Also, there are some cosmetic changes. - Change the output of -v option from "starting full vacuum..." to "starting vacuum accounts..." in reflection of the fact. - Shape duplicated error checks into executeStatement(). There is a big performance win in "COPY with no WAL" feature. Thanks for the efforts! --------------------------------------------------------------------------
