PostgreSQL database instance ‘log_min_duration_statement’ database flag should be set to ‘-1’ (disabled)


The PostgreSQL database instance flag ‘log_min_duration_statement’ defines the minimum amount of execution time of a SQL statement in milliseconds where the total duration of the statement is logged. Ensure this flag is disabled by setting it to -1. This means there will be no logging of SQL statements because some may include sensitive information that should be not be recorded in logs.
