How to Set Up a Mechanism to Capture pg_stat_statements in a Persistent Table

To capture `pg_stat_statements` data from all nodes in a persistent table, set up database objects, including a table and sequence, to collect the data. The data is then captured by inserting it into the table using a PostgreSQL query. The output can be validated by querying the table for specific columns. This allows for performance analysis of queries executed on the database, providing insights into query execution times and resource utilization.
