Namespaces
namespace	storages
	Components, clients and helpers for different databases and storages.
namespace	storages::postgres
	Top namespace for uPg driver.
namespace	storages::postgres::io
	uPg input-output.
namespace	storages::postgres::io::traits
	uPg input-output traits.

Typedefs
using	storages::postgres::ClockType = std::chrono::system_clock
using	storages::postgres::TimePoint = ClockType::time_point
	Corresponds to TIMESTAMP WITHOUT TIME ZONE (value in absolute time (no TZ offset)).
using	storages::postgres::TimePointTz = ::utils::StrongTypedef< struct TimestampWithTz, TimePoint, ::utils::StrongTypedefOps::kCompareTransparent >
	Corresponds to TIMESTAMP WITH TIME ZONE (value in absolute time (no TZ offset)). Time zones are applied automatically.
using	storages::postgres::IntervalType = std::chrono::microseconds

Functions
TimePoint	storages::postgres::PostgresEpochTimePoint ()
	Postgres epoch timestamp (2000-01-01 00:00 UTC)

Variables
constexpr TimePoint	storages::postgres::kTimestampPositiveInfinity = TimePoint::max()
constexpr TimePoint	storages::postgres::kTimestampNegativeInfinity = TimePoint::min()
