sqlpp11/tests/postgresql/usage/DateTime.cpp
Roland Bock 4c942600bb Started to migrate postgresql connector into sqlpp11 repo.
Removed timezone handling in the process (needs to be documented).
Note: on_conflict does not check for constraints (needs to be documented).
Note: some of the constraints tests seem to be aiming for a different static_assert.
