I chose to perform the checks in insert_*_record() functions to keep
them at a central place instead of dispersing all over like the
check_* functions. The latter need to peform their checks considering
the overall shape of the property graph, however, the specification
checks are fairly local - like duplicate property or label names
specified in the same command or duplicate labels being inserted -
they won't usually need checks across labels or elements for example.
I am afraid we might have to sprinkle pre_check_* functions at
multiple places - thus leading to a risk of missing places as this
code evolves.

Do you expect insert_element_record() to perform sanity checks of
labels or insert_label_record() to perform sanity checks on
properties? Or do you expect a hierarchy of pre_check_ functions
cascading from elements to labels to properties?
