I am connecting to postgres 6.4.2 on rh linux 5.2, using new kernel 2.2.2,
from access97 on a win98 machine through an obdc driver (somehow, that was
a mouthful!). I am converting some access files into postgres. One file
in particular has a NOTES field in it (access memo datatype, postgres text
datatype) that may have large amounts of data in various records. When I
run an insert query to insert into the postgres tables from the access
table, it bombs when it hits a record with"too much data" - I get the error
message "tuple size too big, size 8360". In the obdc driver, I tried
increasing the "text as longvarchar" amount to 15000 - no good. I then
tried just unchecking the "text as longvarchar" option - no good. I think
the message is coming from postgres, not the obdc driver. I have found a
record in particular that causes the problem. When I remove a few lines
from the data, it pulls in just fine. The few lines I removed had no
special characters, etc. what to do?? I need to be able to store this
data in its entirety. How to increase the allowable "tuple" size? What is
a tuple anyway??

The data for that notes field is probably making the overall size of the query
too big for the backend to handle. It has a limit of around 8k. The real
solution is to have the driver use a large object instead of in-line the data.
I know I have said this before, but I will try to add that option next since it
seems to be really necessary now, alot of people need to store large amounts of
character data.

hmmm, so in the next driver I will be able to store 80k of chars
in a field of type text ? (sound good)
