TEXT and BLOBS

I want to find out how confused I am. ;-)
I'm testing something on a Postgres 7.0.2 database. I made a small table with
two columns, one serial and the other TEXT, and tried to make serveral
inserts with PHP.
Some went OK, until I tried to insert a large amount of text. It failed. Of
course, I did it on porpose to check the 8 K tuple limitation.
Until here, am I right?
So, now I'm gonna try to make inserts to a table just like the other one, but
with the slight change of making the text column a oid column.
The questions are:
1) where are the blobs stored?
2) Is it posible to insert a chunk of text that has not been saved to a file?
3) where is all the documentation on the behave of BLOBS? All I have found
was in Bruce's book. I couldn't find such things in the users documentations.

TIA
