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.

I wonder how difficult it would have been to create SQL functions out of what is basically psql or pg_dump magic.

If you ignore the answers on StackOverflow that say to use pg_dump and "psql -E", there must be close to 10 other answers with various SQL functions which do exactly that here:

I recommend you read through them and test them to find the best version. I hope one of them fits your needs. If so, I hope you report back here with which one you went with. :-)

Hoping this helps,
