The manual contains a warning about it:
While pg_resetwal will set the WAL starting address
beyond the latest existing WAL segment file, some segment size changes
can cause previous WAL file names to be reused. It is recommended to
use -l together with this option to manually set the
WAL starting address if WAL file name overlap will cause problems with
your archiving strategy.
