You were correct below trigger worked. Giving reference for others.
CREATE OR REPLACE FUNCTION init() RETURNS TEXT AS $$
my $raw_row = "(\"col1\", \"col2\")";
my @new_row = ('5', '6');
my @col_types = ("integer", "character varying");
my $query = "INSERT INTO mytable $raw_row VALUES (\$1, \$2)";
my $prepared = spi_prepare($query, @col_types);
spi_exec_prepared($prepared, @new_row);
return "success";
$$ LANGUAGE plperl;
Thanks, Paresh
