Description: 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.
