What Pg version are you using?
On which platform?
32-bit or 64-bit OS? If 64-bit, with a 32-bit or 64-bit build of
PostgreSQL?
psql (PostgreSQL) 9.0.4
64 bit fedora:
Fedora release 14 (Laughlin)
Linux mybox 2.6.35.14-95.fc14.x86_64 #1 SMP Tue Aug 16 21:01:58 UTC
2011
x86_64 x86_64 x86_64 GNU/Linux
I presume my build of PostgreSQL is x64 - ldd `which psql` spits out
lots of
references to lib64.
sending ~1GB bytea values is borderline crazy, and is completely
crazy
if you are not absolutely sure the transmission is not 100% binary.
I
don't know if the JDBC sends/receives bytea as binary, but it may
not.
If not, you might have better luck with the large object interface.

"Crazy"? I thought that official stand was to keep such crazy values as
TOAST, and LOB interface isn't something worth of usage.
You have exposed such interface, and you firm it. Does this crazynies
is measured by fixed amount above 500MB or it's fuzzy measured with
standard deviation near 1GB? If I use bytea to store such values, looks
I'm crazy too. Sorry, for thinking that documentation is trust worthy.
Thanks for mobilization - I reserved moderngres domains. I think it's
about 1-2 week for making some infrastructure for this.
