replay PostgreSQL log files
Reads a PostgreSQL log file (*not* a WAL file), extracts the SQL statements and executes them in the same order and with the original timing against a PostgreSQL database. If the execution of statements gets behind schedule, warning messages are issued that indicate that the server cannot handle the load in a timely fashion. A final report gives you a useful statistical analysis of your workload and its execution. The idea is to replay a real-world database workload as exactly as possible. This is useful for performance tests, particularly in the following situations: - You want to compare the performance of your PostgreSQL application on different hardware or different operating systems. - You want to upgrade your database and want to make sure that the new database version does not suffer from performance regressions that affect you.
