Why do you think that it would be difficult to do it with the existing code? Actually I wanted to implement this for 8.1. I've already had a quick look at it. My idea was to allow something like "EXECUTE SELECT INTO var1, var2 col1 col2 FROM ...". The code would have to parse the list of variables and check if they match pl/pgsql variables, execute the query (without the INTO stuff of course) via SPI and copy back the results, checking type mismatches or a mismatch in the number of columns. I haven't thought about more complex types however. Did I miss something? Which other limitations are there in the current implementation of pl/pgsql?
