I just confirmed that there are duplicate p-keys in the source table :(.
Three currently but last week there were six. Just FYI I am not 100%
sure pg rebuilt the p-key with dups in it...I need to double check this.

I keep a timestamp on every row for last modified date:

' 00136860' and prl_seq_no
in (20, 23);

There have been no schema changes since 9/15...
