Обсуждение: create table like syntax

is there a syntax that would look something like:

     create table newTable like oldTable without indexes || records ||
constraints with indexes || records || constraints

built into postgres?

What do you want to do with it?  If I understand what you want to do, it
is supported as long as you use ; in place of your ||.

Try this:

create table newTable as
select * from oldTable limit 0;

Well, I should say that the with and without should probably be mutually
exclusive.  I don't know, haven't thought about it that much, but I find
myself creating a lot of the same table over and over from time to time
as I try to analyze some data.  Would be nice to say, hey, create a copy
of this table with indexes and possibly records and constraints.  Or
just a bare copy or something like that, but have a lot of different
options for this kind of thing.
