Thanks a lot, this was the solution.
It would be greate, if you could also show me a way to extract the
inserted binary object from the table on the server to a file on a client.

Hello everybody out there using python,
For the insertion of pictures into my PostgreSQL database [with table
foo created by SQL command "CREATE TABLE foo (bmp BYTEA)], I've written
the following script:
#!/usr/bin/python
import psycopg2
try:
conn = psycopg2.connect("dbname='postgres' user='postgres'
host='localhost' password='data'");
except:
print "I am unable to connect to the database"
cur = conn.cursor()
f = open("test.bmp", 'rb')
myfile = f.read()
try:
cur.execute("INSERT INTO foo VALUES (%s)",(buffer(myfile),))
except:
print "Insert unsuccessful"
"python script.py" runs the script without any errors or messages.
However, the SQL command "SELECT * FROM foo" returns the output "foo (0
rows)" with no entries in the table.
I'm using Python 2.7 and PostgreSQL 8.3.
Could anyone help me to find a way to pin down the problem?
Perhaps you need to conn.commit() your changes.
