Thanks to all who responded. I appreciate it very much.
Yes, that is a good idea. I wasn't sure how to use the NULL clause of the copy command, but I did wonder about other
nullvalues in the data set. There are many as this database grew up over 15+ years of use and many renditions of the
clientapplication.
I am not familiar with sed, except for some trivial bits I nicked off the web. Enough to know it works, and to be
dangerous.Nonetheless, using SED may be the way to go as there are two tables that contain a bit over 3,000,000 rows
each.
