I am using postgres-8.2.3, i have changed my
postgres.c file, in the function PostgresMain in the
case P of processing the command so that, whenever i
see a  word say "tiger" as the first word of the
query, i will generate 10,000 inserts into a table and
execute them using exec_simple.

I will fire one query through jdbc beginning with the
same word "tiger".
Here after inserting 5600 inserts i get the above
ERROR  message.
Any idea how to succesfully insert all those values.

Regards,
Ashwin
