A few modifications on parser_pg's parser_create doctests:
For sql0, the output of having_clause changed from 'foo=bar' to '(foo=bar)'
For sql9, the original output of the first table's alias is wrong, so it's modified from 'FULL' to 'testjoin1', it's join type is also changed from 'INNER JOIN' to 'FULL JOIN'
