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...

Hi
I have a transaction requirement that spawns across components. Typical
example is saving address, order etc. Each of these components will do
their part of transaction. If any of the transactions failed, then all
the transactions have to be rolled back. One way is to go for COM+
transaction using ServicedComponent. But this affects performance and
moreover we have no across database transactions. Another way I found is

Hello ppl,
Imagine some online system, based on PgSql. There are 'many' parts which
depends on each other. I will give small example, but instead of simple
table imagine changing tenths various tables (editing). So, 'change table A'
can be work for hours.
There are tables tableA and tableB. Changes are made by thin client. If
you change tableA, you have to also change tableB to 'finish' operation.
Between starting changing tableA...

I've implemented transactions in my dotNet 2.0 project using
System.Transactions and TransactionScope.

TransactionOptions options = new TransactionOptions();
options.IsolationLevel = System.Transactions.IsolationLevel.Serializable;
options.Timeout = new TimeSpan(0, 5, 0);
using (TransactionScope transactionScope = new
TransactionScope(TransactionScopeOption.Required, options))

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
