Hi,
i recently migrated from mysql to postgresql and did use severel python
postgres-modules. All do what they are designed for, so which one would
you use? psycopg, pygresql, pypgsql? psycopg seems to be the best
solution for heavy traffic/multiple connections .... i have no real
testing environment, so any advice which one to use for different
usecases would be nice.
Thanks, Roland

Hi Roland,
We've been using psycopg (via Zope and straight Python programs) for about a
year and haven't had any problems at all. We don't store much binary data so I
don't know how well psycopg handles blobs and what-not, but performance and
reliability has been fine.
I have no idea how psycopg stacks up against the others; in the end we chose it
because the project appeared to be active, it was easy enough to set up, and a
few test scripts we made all worked (how's that for rigorous evaluation? ;-) ).
HTH,

Hi,
I'm looking for a Postgres connection Python module that has good
support for the BYTEA type.
By good support I mean that
-it should have a function to escape the raw binary data as appropriate.
-it must not choke on some rather large 20-30MB files.
-Retrieval using Select statements should be transparent (or pretty simple)

Hi,
I have postgres 7.4.1 running on my server and I've been trying to find
a good python-postgres interface module. I installed Pygres on another
machine running Linux using a RPM release and it works. However, I need
to do the same for an alpha server and I can't find source files for
PyGres that would compile with 7.4.1 anywhere. Can someone please help
me out? I need a good postgres python interface to work with.
Cheers,

The latest Windows distribution of Python 2.4.2 is using the
msvcrt71.dll, while PostgreSQL is using msvcrt.dll.
This lead to the following problem:
I was using PyGreSQL to connect to the PostgreSQL database. There is a
function that prints a query object q simply by writing: "print q". What
happens on the lower levels is that PyObject_Print(q, stdout) is called,
where stdout is the stdout file descriptor of msvcrt71.dll. Then,...

Hi,
I want to write a small system that is transaction based.
I want to split the GUI front end data entry away from the file handling and
record keeping.
Now it seems almost trivially easy using the sockets module to communicate
between machines on the same LAN, so that I want to do the record keeping on one
machine.

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.
