Minor errors in plpgsql and plperl examples..

Hi -

There are two errors involving single quotes in the following documents.

http://www.postgresql.org/docs/user/c40874340.htm
- In the code for "PL/pgSQL Trigger Procedure" the initial single quote is
missing. Currently the line reads:

CREATE FUNCTION emp_stamp () RETURNS OPAQUE AS

All the other examples have a single quote right after "AS".

http://www.postgresql.org/docs/user/pl-perl4538.htm
- The last example is:

CREATE FUNCTION empcomp(employee) returns int4
AS 'my $emp = shift;
return $emp->{'basesalary'} + $emp->{'bonus'};'
LANGUAGE 'plperl';

Shouldn't the single quotes on the "return" line be escaped?

(i've never used postgresql so maybe this is all incorrect, but just
reading through the docs -- which are very very nice btw)
