56884dc700 Remove Value::DoubleQuotedString 
...and parser support for the corresponding token, as "..." in SQL[*] is
not a literal string like we parse it - but a quoted identifier (which I
intend to implement later).

[*] in all the RBDMSes I know, except for sqlite which has complex rules
in the name of "compatibility": https://www.sqlite.org/lang_keywords.html

efdbf0f9dc Remove Token::Identifier match arm from parse_value 
An identifier is not a literal value, and parse_value is not called on
such a token anyway.

d0a65ffd05 Remove Token::String, as it's never emitted 
Indeed, given that there is Token::SingleQuotedString and
Token::Identifier, there's no other "string" that would make sense...

b3ab4aca88 Use expect_keyword() instead of consume_token() where appropriate 
Before this missing keywords THEN/WHEN/AS would be parsed as if they
were in the text as the code didn't check the return value of
consume_token() - see upcoming commit.

de4ccd3cb7 Fail when expected keyword is not found 
Add #[must_use] to warn against unchecked results of parse_keyword/s in
the future.

89cfa9e599 Don't consume a second DoubleColon in parse_pg_cast

3b13e153a8 Fix parse_time() handling of fractional seconds 
There's no Token::Period in such situation, so fractional part (from sec) was silently truncated.

Can't uncomment the test yet, because parse_timestamp() is effectively
unused: the code added to parse_value() in 5abd9e7dec
was wrong as it attempted to handle unquoted date/time literals. One
part of it was commented out earlier, the other can't work as far as I
can see, as it tries to parse a Number token - `([0-9]|\.)+` - as a
timestamp, so I removed it as well.

eff92a2dc1 Remove special handling of ::type1::type2 from parse_pg_cast 
...it gets handled just as well by the infix parser.
(Add a test while we're at it.)

f21cd697c3 Simplify custom datatypes handling and add a test 
1) Simplified the bit in parse_datatype()
2) Made sure it was covered by the test (the "public.year" bit)
2a) ...the rest of changes in the test are to fix incorrect variable
 names: c_name/c_lat/c_lng were copy-pasted from a previous test.
3) Removed the branch from parse_pg_cast, which duplicated what
parse_data_type already handled (added in the same commit even
2007995938 )

other completely.
