These used to work:
regression=> select %f.f1 FROM FLOAT8_TBL f;
ERROR: parser: parse error at or near "%"
regression=> select f.f1 % FROM FLOAT8_TBL f;
ERROR: parser: parse error at or near "from"
This is causing the float8 regress test to fail.
I suspect this has to do with Bruce's recent hacking on operator
associativity.
