Hi,
Inside a stored procedure EXECUTE runs a dynamic query,
DOCS SAY:
Oftentimes you will want to generate dynamic commands inside your PL/pgSQL functions, that is, commands that will involve different tables or different data types each time they are executed. PL/pgSQL's normal attempts to cache plans for commands will not work in such scenarios. To handle this sort of problem, the EXECUTE statement is provided:
EXECUTE command-string;
where command-string is an _expression_ yielding a string (of type text) containing the command to be executed. This string is fed literally to the SQL engine.
Really not sure how to execute a named plan inside plpgsql.
