It would be nice if there was a way to pass dynamically formed records
around, similar to how you can pass the results of row() around. Someone
else has actually be asking about this at
https://github.com/decibel/pg_lambda/issues/1.
BTW, there's no advantage I can think of to using plpgsql just to return
the output of a query. You'd be better off using a SQL function instead.
Actually, I guess the plan for the plpgsql version would be cached; I'm
not sure if the same is true for SQL functions. But you'd probably need
a more complex query for that to be a win over the lighter weight nature
of SQL functions.
