Autovacuum Launcher Process Exception

Hello,

I have been running PostgreSQL for many months and just recently started
getting this exception upon start up.  Does anyone know what the issue
might be?

LOG:   database system is ready to accept connections
LOG:   autovacuum launcher started
LOG:   autovacuum launcher process <PID 7060> was terminated by exception
0xC0000006
HINT:   See C include file "ntstatus.h" for a description of the
hexadecimal value.
LOG:   terminating any other active server processes
LOG:   could not open temporary statistics file "global/pgstat.tmp": No
such file or directory
LOG:   all server processes terminated; reinitializing
PANIC:   could not open control file "global/pg_control": No such file or
directory

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
