Attached is the updated version of the patch (the original description
is here: http://archives.postgresql.org/pgsql-hackers/2009-07/msg01332.php)
that doesn't use global variables. It also shows the last line of
the context in the example above correctly:

psql (8.5devel)
Type "help" for help.

test=# select perl_log2();
NOTICE: Test from function two
CONTEXT: PL/Perl function "perl_log2"
NOTICE: Test from function one
CONTEXT: PL/Perl function "perl_log1"
SQL statement "SELECT * FROM perl_log1()"
PL/Perl function "perl_log2"
perl_log2
