Novice Question

Sorry, I meant to ask about copying databases, not tables (including all
data in the database as per below).

Thanks,

What kind of command would I run if I wanted to copy an entire table
(along with renaming it, and, of course, all data from the first table
- some of which is binary)?

Thanks,

select * into table new_table from old_table;

That's it.

SELECT * INTO newtable FROM oldtable;

Note that this doesn't construct indexes, Foreign keys, constraints,
etc.

If by 'binary data' you mean BLOBs, I'd expect the above to work.
Other than that, AFAIUI you have no reasonable expectation that your data is
stored in any meaningful binary format by the database. All data
could be internally stored as strings (though that might be very
slow).

you sure about that syntax?

How about:
create table new_table as select * from old_table;

you can do a pg_dump your_database>your_database.dump.sql
and then createdb to create your new database, and finally
pgsql -f your_database.dump.sql new_database

and that's it. you should probably use -Upostgres
depending on what kind of security you use.

create database newdb template olddb;

works as well.
