These two logging formats are each produced by different parameters:

These lines always have duration prefixes.

This is produced by log_statement = 'all'
These lines never have durations.
If you want the matching durations, use log_duration = on and read the
manual to see how to match them up.
The same statement can be logged twice using those options.

Does that answer your query?
