Thanks Michael,

I suppose I should have checked the docs for CREATE TABLE AS and not just CREATE TABLE :)

Regards,
Daniel

This works as intended, CREATE TABLE AS does not support IF NOT EXISTS
in 9.4 and 9.3:
http://www.postgresql.org/docs/9.3/static/sql-createtableas.html
http://www.postgresql.org/docs/9.4/static/sql-createtableas.html
But it does in 9.5 and onwards:
http://www.postgresql.org/docs/devel/static/sql-createtableas.html
