Error while upgrading from v12 to v13

I am getting below error while upgrading postgres from version 12 to 13 and
not sure how to enable the function before upgrading the cluster. Can you
please help me to resolve this.

 error: could not execute query: ERROR:  could not find function
"pl_profiler_enable" in file
"/usr/lib/postgresql/13/lib/plprofiler.so"
Command was: CREATE FUNCTION "public"."pl_profiler_enable"("enabled"
boolean) RETURNS boolean
    LANGUAGE "c"
    AS '$libdir/plprofiler', 'pl_profiler_enable';
