Let's say I've got a table of bios, so :

last_name text not null,
person_title text,
person_short_bio text

Now, the "natural order" would be a standard "select * from bios

The overall premise is that the latest version is the current version unless a

Hi,
Am looking to compile some software that will make use of Postgresql libraries.
However doing "apt-cache search postgresql-11-*" I can't see any libs or dev
package ?
Would installing "postgresql-client-11" be sufficient ? I don't really want
to go installing the whole shebang.
