Ed,

Actually that's where I started. Most of the answers on
StackOverflow either don't work on the latest versions of PostgreSQL or
didn't include the complete DDL. Most were missing indices and
constraints. As a previous poster remarked, psql -E and then copy/pasting
and using that as the basis for custom function(s) seems to be my only path
forward.

It's a shame that users are basically forced to write not entirely
simplistic SQL themselves. The SQL appears to already exist in PostgreSQL
as evidenced by the results of psql -E, it just doesn't seem that it was
packaged into user accessible SQL functions. I've noticed that the answer
to many questions seem to be "use this psql \ command". Is there any
reason that all of the special psql magic functions couldn't be exposed as
default SQL functions?

Oh, well. Thanks for all the help.
rik.
