Because plpgsql functions are compiled on first execution and all queries
are then prepared. All tables are referenced directly in prepared
statements, not by name. Any prepared statement that refers to dropped
tables (even dropped temp tables) is thus unfit for consumption.
This allows queries in plpgsql functions to be extremely fast, but it
isn't smart enough (yet) to recompile functions when a table the function
depends on is dropped.
Just disconnect and reconnect, all prepared plans will be lost, and it
will work. Or issue your queries directly instead of using a function.
