Yes you should use the pg_resetwal what it does is clears the write-ahead
log (WAL) and optionally resets some other control information stored in
the pg_control file. This function is sometimes needed if these files have
become corrupted. It should be used only as a last resort, when the server
will not start due to such corruption.
