[postgis-users] Except

[Matt Doughty]

Thanks for the ideas. At the moment I'm trying to go with the 'array as text' suggested by George although I have to admit I haven't got very far yet.

PS: Sorry for sending a SQL question to the PostGIS list- shan't happen again (although I must say the members of this list have been particulary helpful!).

Sorry, my bad... I misread your question. 

You might be able to write a plpgsql function that went looking at the 
system tables for a list of all your columns for a given table and then 
build a query using the columns of your choice.
