Simplified syntax for multi_columns a lot
...
Instead of
multi_column(alias, columns...)
it is now
multi_column(columns...).as(alias)
Also, you can now write:
all_of(table).as(alias)

All statements back to composite design

The point is that even though the CRTP code looked nice, it was too hard

Moved a bunch of things into namespace vendor

This namespace is for things the developer will not get in touch with

Replaced implicit trivial_value_is_null tag for columns with explicit tvin method

This isn't database vendor specific, but library vendor specific, as I

Everything that is interpreted also has to move out of detail namespace,

Stripped a lot of superfluouos type information from result rows.
...
Moved member template into name class to utilize the fact the class
aliases are really just aliases.
This makes the code leaner in many cases and less complex for the compiler
(I guess). It also has the benefit, that the field name is available as
string in the result_rows. This might be useful for debugging one day.

Introduced field template to make result_row_t less specific.
...
It is sufficient to have name and type. There is no need for the result
"to know" what exact expression was used to define the column.
Surprisingly, template alias creates new templates (in contrast to
non-template using, which really just creates an alias of a type).
template<typename T> struct A{};
struct X
{
template<typename T>
using U = A<T>;
};
struct Y
{
template<typename T>
using U = A<T>;
template<>
using U<int> = X;
};
template<template<typename> class X>
struct Z{};
static_assert(std::is_same<X::U<int>, Y::U<int>>::value, "class aliases are really just aliases");
static_assert(not std::is_same<Z<X::U>, Z<Y::U>>::value, "template aliases are new templates");
