This method inserts values into the table specified filling in the
values from the dictionary. It then reloads the dictionary with the
values from the database. This causes the dictionary to be updated
with values that are modified by rules, triggers, etc.
Due to the way that this function works you will find inserts
taking longer and longer as your table gets bigger. To
overcome this problem simply add an index onto the OID of any
table that you think may get large over time.
