Also, when I speak of "unique identifier" I'm not speaking of the one if your FINAL tables, I assume you would have at least the *_id field as PKEY, so nothing else needed, but the one in your SOURCE data set (it can be anything, like the row number in the original excel).
Francisco/Jeremy, I'm grateful for you patient help. The 'unique identifier' in the source file has been provided (just now) using nl <https://ss64.com/bash/nl.html>. The syntax I used is: nl -b a -n ln -s , -v 339 source.txt > out.txt because the organizations table has 338 as the maximum org_id number. I believe this fulfills the need for a known unique ID in the source file, and when I parse each row using gawk to create the two files for table input I can use it in both the organizations table (as the PK) and the people table (as the FK referring to the organizations table). I can let postgres assign the unique ID for the new rows in the people table. Am I still missing something critical?
MMM, apart from angel dust I do not know what PCP could stand for.
