You are mixing something up.
A hyperlink or any form of URL is just a string. It's as such not magic
or active as long it gets interpreted as an URL and tossed to a suitable
You find a "hyperlink" datatype in MS-Access. Thats still just a simple
varchar where Access has the additional information that it should throw
it to the program that is registered as your web-browser in your
Access doesn't even check wether the inserted text conforms with the
rules for hyperlinks. You could store poems in such hyperlink columns
and still IE won't hop anywhere if you click on the nicely blue
Anyway ... this data type might be useful in Access does provide an data
manipulation interface in sense of forms or "tables" which are in
essence forms, too.
PostgreSQL is a storage engine that can keep your hyperlink-strings
ready but it doesn't have an interpreting interface.
So PostgreSQL shows no data where you could click on and it has no idea
about the client's environment like his favourite browser.
So store URLs in varchars and let the client software interpret the data
as "active" hyperlink.

Where and how is the data displayd?
If you type an SQL query into psql you shouldn't wonder that the
textmode output is not clickable.
If you have a more comfortable program to view the data, you might be
able to tell it this column holds URLs.
There's a good chance you even don't need the "http://" in front of the
You might run into trouble with some brain dead web servers that won't
accept "domain.com" but require "www.domain.com".
And there are URLs that won't work with the "www." like "dict.leo.org".

If your client interface is a web-application where some script language
like PHP pulls data out of the DBMS and processes it dynamically to HTML
then and just then will those HTML-link-tags be of any use.
In this case you store the domain "www.domain.com" probaply with
additional info like the description and an alt-text in varchars.
On runtime you let a script assemble the complete link-tag and integrate
it in the HTML output.
"dict.leo.org" + "online dictionary" + "click here for wisdom" + scripting
<a href="http://dict.leo.org" alt="click here for wisdom"

The DBMS couldn't care less if the stored data is just a domain or a
complete HTML tag.
