Informix Schema -> PostgreSQL ?

I am an ex-Informix convert.  Informix used the term "schema" to refer 
to the SQL-format definition of how a table or view was created.  E.g., 
CREATE TABLE john ( char(8) lid, ...);  Some views we have are quite 
complex (and not created by me) and I want to create a similar one in 
Pg.  If I could see the view in this SQL format, then I could use SQL to 
create another one using this as a template.

pgadmin3 can show this definition in SQL format, but I can't use 
pgadmin3 on a certain box.  How can I show information in Pg (psql) the 
way that Informix would show a schema?

BTW, what does PostgreSQL call this (what Informix calls a schema)??
