[Please CC any replies, thanks] Hi,
I got this nice error, and according to Tom Lane[1]: > Depending on what PG version you're using (which you did not say, > naughty naughty) there are paths in interactive query entry that > might try to execute datatype input functions before setting the > query snapshot. But I don't believe it can happen down inside SPI. [1] http://www.dbforums.com/archive/index.php/t-1065541.html Good guess, I am inside a type input function trying to use SPI. My questions are: - I'm using 7.4, is this fixed/changed in later versions? - I'm triggering it with: select 'hello'::mytype; Is there an easy way of testing my function without triggering this? select (select 'hello'::mytype); -- Same problem select (select 'hello')::mytype -- gives something about casting unknown \copy .. from stdin -- Works but is inconvenient - Is there a way to detect if a snapshot has been started and creating one if there hasn't. I've seen the snapshot related functions but I don't feel comfortable sticking them in my type input function just to fix this. Is it safe?
