Hi,

I found the following error message misleading:

test=# create table cows2 (LIKE cows);
ERROR: inherited relation "cows" is not a table
STATEMENT: create table cows2 (LIKE cows);

I'm not trying to inherit a relation, I'm trying to base a table on
it. As it happens, "cows" is a foreign table, which *is* a table,
just not a regular table. It might be useful to add support to clone
foreign tables into regular tables, the use-case being that you may
wish to import all the data locally into a table of the same
structure. But the gripe here is the suggestion that the relation
would have been inherited, which would actually be achieved using
INHERITS.
