Don't you have problem with geting whole data correctly? There
is bug in psqlodbc driver when reading data from text field larger
then 2048 (+-) bytes (in Unicode driver). The problem was fixed
in 08.01.0106 development snapshot.

Are you sure the PgAdmin returns all rows (I'm not). Maybe Dave
give us the answer.

I don't know it exactly. Could you try experiment with parameters
such Use declare/fetch or Server side prepare?
It could help me when you send me the mylog output (enable the mylog
output under Global and DataSource button).
I hope the data isn't confidental (they are listed in mylog output).
