Postgres BLOBS and PHP

Don't know if this is the right place to ask this but here I go:
Lets say I got a database with 4 tables, each one with a diferent oid field.
Now, maybe I haven't read enough, or the docs aren't that good (PHP docs),
but I can't find out how to open a blob that will write to a determined iod
field of a determined table. Any ideas?

What I want to insert and read are large chunks of text. Will Postgres 7.1 be
able to store any size of tuples? I mean, I have heard about compresion and
other things in the TOAST threads, but will this only pull up the 8K row size
limit to a larger size, or will it let me store any size of rows?

Saludos... ;-)
