Well, there are system funcs and such too, check out https://www.postgresql.org/docs/15/functions-info.html.
See Table 9.71. System Catalog Information Functions
pg_get_constraintdef()
pg_get_functiondef()
pg_get_indexdef()
pg_get_triggerdef()
pg_get_viewdef()
...

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.On Mon, Mar 20, 2023 at 2:33 AM Edward J.

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,Ed
