It's fairly silly to truncate the throttle_delay to integer when the only math we ever do with it requires converting back to double. Furthermore, given that people are starting to complain about restrictions like only supporting 1K client connections, I don't think we're very far away from situations where the precision loss matters. As the code stood, for example, there's no difference between --rate 100001 and --rate 111111; both get converted to throttle_delay = 9. Somebody trying to run 100 threads and have each one dispatch around 1K TPS would find this lack of precision rather surprising, especially since the required per-thread delays are around 1ms, well within the timing precision of modern systems. |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
