Pggraph

All plpgsql functions will need two new arguments, and one removed argument:

start DATE, end DATE, and removal of offset INT.

The functions will be altered in the following ways:

• Determining the length of the WHILE loop from the date ranges, if present, instead of using the interval to calculate it.
• Alter the queries to use the start DATE parameter to position the start of the set, and then utilize the WHILE loop to offset from that point, ie, WHERE date = date_start + (interval * iterations)::interval
