Bug corrected and PGSQL/MySQL operators

Hi Dave,

I've corrected a bug in my code inside motoX_array_lval that caused the s=
tack=20
to grow forever ... the bug has shown up while implementing PGSQL/MySQL=20
overloaded operator. Do you (Dave, Shay, Cory) think these operator make=20
sense?

++ and -- on rset instead of rset.next(), rset.prev()
[int] and [string ]instead of rset.getString(int) and rset.getString(stri=
ng)

So now you could write:

while(rset++){
=09for(j=3D0;j<rset.columns();j++)
=09=09print (j=3D=3D0?"|":"")+pad(rset[j],15)+ "|";
=09print "\n";
=09i++;
}

and

while(rset++){
=09print (rset["name"])+ "|";
=09print "\n";
=09i++;
}
