   No,  because  the  querystring  length  is unlimited, but the   protocol  for  sending  the  information  to  the
statistic  collector daemon uses a compile time maximum buffer size.
 
   You  can  increase  that  buffer  size  to  see  more of your   querystring. It is by default
       src/include/pgstat.h:       #define PGSTAT_ACTIVITY_SIZE    256
