--------------------------------

Sorry, didn't notice there were failures in QueryParserTest. Could you please review the changes
I made in QueryParserTest, [~jamestaylor]? Not sure if they are all reasonable test adjustment.

> You should be able to select any "generator" type function from Phoenix without specifying
a table.  For instance a sequence needs an arbitrary potentially unrelated table just to get
the next value.  The fix should enable queries like this:
> {code}
> SELECT NEXT VALUE FOR my_seq
> {code}
