I'm not much of a Perl hacker, but even I can see that this is not good
Perl.  You need a semicolon to finish the return statement, and I think
you want to manipulate the first element of the @_ array, not the whole
array.  So something like

CREATE or REPLACE FUNCTION remspace(TEXT) RETURN TEXT AS '
    $_[0] =~ s/\s*//;
    return $_[0];
' LANGUAGE 'plperl';

would probably do what you want.

I'd recommend getting hold of a book about Perl.
