Transaction Wraparound Report(Postgres)

Transaction wraparound is a significant challenge in PostgreSQL, and this new feature is designed to help analyze and predict it. For a given database, it provides the percentage progress toward wraparound and identifies potential issues such as idle transactions, inactive replication slots, and other factors that may be hindering the freezing process

Identifying the problem database

Once you identify that this issue is occurring, you'll likely want to know which database is responsible. The table below in the report highlights the top 5 databases contributing to the problem

Transactions Per Seconds Vs Time to hit wraparound point (Reference table)

The reference table below provides an estimate of the time required to exhaust 2 billion transactions.

Note: Calculate your transactions per second (TPS) during peak workload periods and compare it with the table. Additionally, identify any factors that might be hindering freezing activity

Wraparound Stats

Below report helps you identify potential issues like idle transactions, inactive replication slots, and other factors that could be slowing down the freezing process
