1073741818 is a bit less than 1GB and 1073741818+32 is a bit more. So
you are obviously hitting a 1GB limit here.
Given that 1GB is the maximum length of a character type value in
PostgreSQL and the error message mentions a "string buffer", I suspect
that your query tries to construct a very long string. Try to rewrite
the query so that it creates several shorter strings instead.
