Hello,
I'm using psycopg to insert records in a number of threads. After the
threads finish, another thread runs to collect the inserted data. Now,
my problem is that psycopg let's my threads end before the inserts
actually took place, resulting in my collecting thread finding no
records... They are inserted after it checks.
Is there a way to tell psycopg or python to wait until the insert took
place?

Good day,
I have a number of threads doing inserts in a table, after which I want
to do a select. This means that it will occur that the row that I want
to select is locked (by the DB). In these cases, I believe I receive an
OperationalError (or is it an InterfaceError?).
Is it possible (and if so - how?) to verify that the exception occured
because of row locking, so that I can wait and try again?

Another python/psycopg question, for which the solution is probably
quite simple; I just don't know where to look.
I have a query that inserts data originating from an utf-8 encoded XML
file. And guess what, it contains utf-8 encoded characters...
Now my problem is that psycopg will only accept queries of type str, so
how do I get my utf-8 encoded data into the DB?
I can't do query.encode('ascii'), that would be similar to:
>>> x =...

Oh no! It's me and transactions again :)
I'm not really sure whether this is a limitation of psycopg or
postgresql. When I use multiple cursors in a transaction, the records
inserted at the start of the transaction aren't visible to those later
on in that transaction (using a different cursor).
Attached is a simplified example (the except's are a bit blunt, I know)
of what I'm trying to do. In reality, the different cursors are...

How do I supress the output generated from each psycopg command:

I had Visual C++ 6.0, so I compiled those
libpq.dll and psycopg.pyd.
if there are anyone to play with
Windows, Python 2.3 and Postgre-8.0.0-beta4 for windows like me.
You cat get those from: http://eino.net/html/python.html
Original psycopg source code is available in:

Hello, I'm new to both PostgreSQL and psycopg and I'm trying to connect
to my database running on localhost. I have postgres setup to do md5
authentication and this works when using a db admin tool on my local
network. For some reason, psycopg fails with IDENT authentication.
>>> import psycopg
>>> psycopg.connect("dbname=jlowery user=jlowery host=localhost
password=XXX")
Traceback (most recent call last):
File "<stdin>", line 1, in ?

Look at this example:
>>> import psycopg
>>> psycopg.__version__
'1.1.19'
>>> import datetime
>>> today = datetime.datetime.today()
>>> co = psycopg.connect('')
>>> cu = co.cursor()

Hi all,
I'm playing a bit with PostgreSQL, in which I've set me the target to
create a python script which with user input creates a new user role and
a database with that owner (connecting to template1 since I know that at
least that db exists).
Ok so I installed PostGreSQL and pygresql since it looked like that this
is endorsed by PG, I had some trouble with the DB-API2 (complains about
there is already a connection to template1,...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
