I'm just starting out using postgresql in specific and sql in general.
I have a table some of whose fields may not be filled in a normal
INSERT, but may be needed at some future time.
I am aware that the whole are of NULLs is somewhat controversial, but
unsure if this means I should implement these in my tables.
I am driving the databases through perl DBI.
