OK, now in 2 lines:

CREATE FUNCTION jmax() RETURNS integer
    AS $_$use strict;

for (my $i=3D0; $i<10000000;$i++) {
        spi_exec_query("select 'foo'");
}
my $j=3D1;$_$
    LANGUAGE plperlu SECURITY DEFINER

running this test and your postmaster eats a lot of memory.
it seems that there is a memory leak  in spi_exec_query :-(=20
