What is pgreplay
pgreplay is:
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:
