I'm using symfony framework, and my db is Postgres. I export data from my tables into XML format. The european characters (those with umlaut) are messed up, inspite of using UTF-8 encoding. Any suggestions on how to fix this?

I have an update routine:
$Query = "UPDATE A SET type=\"" . $strType . "\" where id=" . intval($ID);
Problem:
When $strType is a string, like "...

I'm adding a new, "NOT NULL" column to my Postgresql database using the following query (sanitized for the Internet):
ALTER TABLE mytable ADD COLUMN mycolumn character varying(50) NOT NULL;
Each time I run this query, I receive the following error message:
ERROR: column "mycolumn" contains null values
I'm stumped. Where am I go...

In postgresql a query in the querylog gets something like this:

Hello, everyone!
I have a problem with simple full-text search dictionary template in Pg. It's simply passes through any non-English words not bothering lower-casing em. Is it by design or I miss some kind of setting here?

I am trying to find a way to have a SELECT statement return the set of dates between 2 input dates with a given interval. I would like to be able to easily change the time frame and interval that would be returned, so hard coding something with a series of SELECT ... UNIONs would not be ideal.
For example: I want all the dates at 5 sec...
I am getting the error OperationalError: FATAL: sorry, too many clients already when using psycopg2. I am calling the close method on my connection instance after I am done with it.

I'm helping implement a SQL Server 2008 database and I have several columns that I'd like to default to the next number in a sequence, but still be able to insert numbers by hand into it at will. In PostgreSQL this is done with the SERIAL datatype and a sequence. Unfortunately those things do not exist in SQL Server. Here's what I know W...

Suppose I've got an album information database. I want to setup the schema in a normalized fashion, so I setup two tables - albums, which has one listing for each album, and songs, which lists all songs contained by albums.

Hi world,
I intend to have a python script do many UPDATEs per second on 2,433,000 rows. I am currently trying to keep the dynamic column in python as a value in a python dict. Yet to keep my python dict synchronized with changes in the other columns is becoming more and more difficult or nonviable.
I know I could put the autovacuum on...

Sometimes when copying stuff into PostgreSQL I get errors that there's invalid byte sequences.
Is there an easy way using either vim or other utilities to detect byte sequences that cause errors such as: invalid invalid byte sequence for encoding "UTF8": 0xde70 and whatnot, and possibly and easy way to do a conversion?
Edit:

I have an existing ASP.NET app which is configured to connect to a MS SQL Server database and I am trying to modify it to use a postgres database instead.
I would like to avoid modifying the C# code, if possible.
I expected that the following changes would be sufficient:

Very simple question (I hope), does there exist a tool similar to phpMyAdmin when working with a MySQL DB but for PostgreSQL databases?
The reason I'm not just googling for a solution is that I am not as familiar with PostgreSQL as I am with MySQL and I was hoping that the SO community would be able to provide a tool that you have exper...
I have been working on an application in Django. To begin with, for simplicity, I had been using sqlite3 for the database.
However, once I moved to PostgreSQL, I've run into a bit of a problem: the primary key does not reset once I clear out a table.
This app is a game that is played over a long time period (weeks). As such, every t...
