How big is "relatively huge"?

the "lo_*" commands are for working with large objects; these have
somewhat unusual semantics compared to the normal data in columns in
PG.  If you're routinely expecting files of more than, say, one MB then
they're probably a good way to go, but it's a lot more work getting them
going in the first place.

If you want to just get the data into a TEXT column as quickly as
possible; I'd probably just write a little bit of code to perform the
escaping that PG requires on the file.  You can then simply do:

  COPY tbl (col) FROM '/path/to/escaped/file';

I'm not sure if this is really what you want though!  "Enormous" TEXT
columns can be a bit fiddly to work.
