Hi, e.g. create table super (name varchar(50)); create table sub (val int4) inherits (super); create table second (name varchar(50), supernr int4 references super(oid)); is there any way to get a chart (er, omt), etc. out of a database? I know that this would be a great programming work but are there any already fixed solutions? The output does not have to be "graphically" a kind of textinfo like: "super is a superclass of sub and offers name to sub" or "table second has a field supernr which is a foreign key of super" would be okay too.
