There are bits of that, but it's not terribly complete or consistent
because nobody's made a concerted effort to build stuff that wasn't
driven by "what does pg_dump need". (And what pg_dump needs, for
the most part, is not simply "give me all the DDL for this object
in a black box".)
I'd suggest taking a look at the pg_get_* functions, which are
mostly documented at
https://www.postgresql.org/docs/current/functions-info.html
There are some other things on that page that might help, too.
regards, tom lane
