[web2py] broken DAL with changeset # (d637c1e36408) possible fix to lack of conformality in PGSQL

[Carlos]

Hi,

DAL is broken for postgresql (9.0 on win7) immediately after applying the 
following changeset:

   # (d637c1e36408) possible fix to lack of conformality in PGSQL

Error at insert:

   sequence item 1: expected string, psycopg2._psycopg.QuotedString found

Traceback:

  File "C:\web2py\gluon\dal.py", line 4858, in insert
    return self._db._adapter.insert(self,self._listify(fields))
  File "C:\web2py\gluon\dal.py", line 880, in insert
    query = self._insert(table,fields)
  File "C:\web2py\gluon\dal.py", line 876, in _insert
    values = ','.join(self.expand(v,f.type) for f,v in fields)
TypeError: sequence item 1: expected string, psycopg2._psycopg.QuotedString 
found

Thanks,

   Carlos
