Title: Quote identifiers to avoid errors with CamelCased table|view|sequences names

If you will have Camel Cased table name e.g: ```tmp.SomeNiceTable```, PostgreSQL is case insensitive when queries are passed by driver but is case sensitive when looks for objects so:

```
SELECT * FROM tmp.SomeNiceTable;
```

results in error:

```
relation "public.somenicetable" does not exist
```

We should use
```
SELECT * FROM tmp."SomeNiceTable";
```
form for queries, ```quote_ident``` do the job for Us, but it is not available
in versions prior to 7.3 (http://www.postgresql.org/docs/7.3/static/functions-string.html)
