Turn Query Logging on in postgresql.conf then see what queries are executed
by pgAdmin or similar when you run it?

But note that these queries are moving targets: they frequently change
from one PG version to the next.

By far the best answer, if you can use it, is to invoke pg_dump itself
as a subprocess.  Something like "pg_dump -s -t mytable ..." for
instance.

If you want to programmaticly discover the elements in a database
schema then you can always query the INFORMATION_SCHEMA:

http://www.postgresql.org/docs/current/static/information-schema.html

That isn't the same as having the raw DLL statements that created
them, but depending on your purpose may be good enough.
