David,

Since the two separate tables have no duplicates I find it difficult to
understand how combining the two generates a duplicate row.

In any case, I always drop the table before running the script after
correcting errors so there should not be a previous row with the same
values. Puzzling,

Information that would be helpful:

The schema of the waterchem table

In particular, what is unique constraint "waterchem_pkey" a constraint on?


Thanks,

Rich
