form contains an image input field and when submitted, the image is
uploaded, resized and added as binary information to a db table. Please
note, I am using a PostgreSQL database
I have written all the code out below that deals with the submission

Hi,
the following I posted already on pgsql-bugs -- perhaps someone has a good
workaround or fix or can say me that I'm wrong?
There seems to be a bug in handling bytea columns with index and the
like-operator.

Hi all,
AFAIK it is possible for columns to be very large, up to about 2 GB. Are
there any hints or experiences about storing binary data (jpg-images,
pdf-documents) in PostgrreSQL with or without the complicated lo-stuff?
Of course it's in many cases a good approach to store those files simply
in the file system but there's always a risk of running out of sync
(filesystem and tables), e.g. by deleting files and not deleting the
table...

Do I need to use the -b option in pg_dump to dump bytea fields? For a while
now I have been routinely using the -b option in pg_dump to back up,
restore, and copy my databases because I thought that this was necessary to
dump bytea fields. I am not using other types of large objects in my
database. Recently, I tried to dump a database with this option and the
dump failed; however I can dump the database without the -b option and my...

I'm attempting to use spamassassin 3.0 (beta) with an SQL backend, and have
identified one performance gain so far that makes PostgreSQL a good (IMO)
candidate for the backend. I need some advice though on another aspect--
instead of storing each token as text in the database, the token is being
sha1()'d and then possibly pack()'d.
That's all just background for my real question-- is there anything in the
standards (or elsewhere) that...

Hi, I am pretty new to Python and trying to use it for a relatively
simple problem of loading a 5 million line text file and converting it
into a few binary files. The text file has a fixed format (like a
punchcard). The columns contain integer, real, and date values. The
output files are the same values in binary. I have to parse the values
and write the binary tuples out into the correct file based on a given
column. It's a little more...

Hello!
I have some postgresql database that stores binary data (windows/linux
executables). Field type I use for this is bytea.
Also I have php script that allows users download these binaries via
their web browser.
That stuff was running on ubuntu 7.10 with postgresql 8.2 and most
recent php version.

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:

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,...
