I found the solution. I was totally wrong about the 4 backslashes.
pgslekt=> delete from short_links;
DELETE 1
pgslekt=> INSERT INTO short_links (link_type, short_link, long_link,
description) VALUES
pgslekt-> ('sk', E'\\[sk=(.+?)\\|(.+?)\\|(.+?)\\]',
pgslekt(> E'<a href="//www.arkivverket.no/URN:sk_read/\\1/\\2" title="Lenke
til bilde av skifteprotokollside">\\3</a>',
pgslekt(> 'Scanned probate registers [sk=protocol|image reference|link
text]');
INSERT 0 1
pgslekt=> select regexp_replace((select source_text from sources where
source_id=23091), (select short_link from long_link from short_links where
link_type = 'sk'), 'g');
regexp_replace

Beautiful. Now I'm going replace this big ugly function with a loop reading
values from a table. I may even write an interface for managing shortlinks :)
