Inserting/updating large text fields w/libpq

Hi folks,

How does one insert large 'text' fields via libpq?  That is, data in
insert/update statements that exceed the 16K limit in stock 7.1.3 setups.

For the moment, I'm iterating over a concat (column = column || 'next chunk'),
but that's ~64 net trips for my average 1meg entries.

I suspect there's a coming, unimplemented API for these types opened up by
TOAST, to obviate Large Objects.  However, to ease current requirements,
I hope I'm doing something really dumb.

Thoughts?

thanks,
-jeremy

Verdict: really dumb.  Directly after posting, I dove into the 7.1.3 code,
curious about the details.  Not finding any such error ("query .. too long"),
it was obviously a link problem.  Sure enough, old, system RedHat libs.
Lots of testing with the right libs & huge input does fine.

Sorry folks.  Please ignore.
