if you has a some modern version of PostgreSQL, you can use a
autoexplain contrib module. just do

load 'auto_explain';
set auto_explain.log_min_duration = 0;
set auto_explain.log_nested_statements = true;

select your_function();

look to log

Pavel Stehule

other solution is just a using a RAISE NOTICE

var := 'SELECT .... ';
RAISE NOTICE '%', var;
EXECUTE var USING ..
