SCD for PostgreSQL

#1

How would I build a SCD if my target database is PostgreSQL? It doesn’t look like it is an option for PostgreSQL? Is the Diff Snap the way to do it?

#2

For anyone wondering, I’m using a Join Snap with an Outer Join.

If a unique ID field from the left side is null but populated on the right side then it is a deleted record.
If a unique ID field from the left side is populated but null on the right side then it is a new record.
If a unique ID field from the left side and right side are both populated then the it is an existing record.
