Here is my insert information:

I set up my datasource as described in the accepted answer here using the postgres bulk uploader.
I have two tables, uxid and productdata.
What works:
In one workflow, I am able to Delete Data and Insert into uxid table and the data shows up successfully.
What doesn't work:
In another workflow, I try Append Existing into productdata and the gallery says that it successfully uploaded 173k records, but the records do not show up in the table.
What I've tried:
I do a before/after record count query and see the count does not change in productdata.
I view the records that are trying to be inserted and confirm they are new so I know records are not simply getting updated.
I tried creating a new blank productdatatest table in case something was locking the first productdata table and I get the same problems.
What in the world is happening here?
I suspect it might by a postgres or server issue, not an alteyrx issue.
