Is the use of array as PL/PGSQL function arguments ?

Hello,

Since it's not possible to do a function with a variable number of arguments, I am wondering if it is possible to use an array as an argument in a PL/PGSQL function ?

CREATE OR REPLACE FUNCTION myownfunction(members.id%TYPE[], events.id%TYPE) RETURNS BOOLEAN AS '
BEGIN
...several sql queries that are OK...
RETURN TRUE;
END;
' LANGUAGE 'plpgsql';

I am currently getting this error : ERROR: parser: parse error at or near "["

But I don't see anything in the documentation that forbids the use of array as arguments. So, did I make a mistake or is it forbidden ?

Thanks in advance :-)
