I notice that one of my tables gets TOASTed, about 40% of it. I read about TOAST and understand the general motivation (get faster access to the *other* columns). But in my case the big column (~2.5KB fixed width) is a list (array) of values (not text) and the usage pattern is that I always access a single row from the table by key and read the full list. So my guess is TOAST is doing me more damage than good. Right?
I would have liked to disable TOAST (even altogether for my DB) - is there a direct way to do this? Alternatively I thought of increasing TOAST_TUPLE_THRESHOLD and TOAST_TUPLE_TARGET from 2KB (I believe this is the default?) to 4KB? Do I have to change the source ( http://doxygen.postgresql.org/tuptoaster_8h-source.html here ?) and compile a private version of Postgres?
