I found this answer elsewhere.
If your DB is on the local host, try leaving the host field blank in the connection as opposed to using “localhost” or “127.0.0.1″. This tells PgAdmin to connect via the local unix socket instead of TCP.
My colleague suggests that Query 1 should run faster than Query 2. If it's true, please anyone explain me the reason. Thanks.
Query (1):
IF ( SELECT COUNT(UnitTrustCounterId)
FROM UnitTrustCounter
WHERE PeriodId = 0
) > 0
SELECT 1
ELSE
SELECT 0
Query (2):
IF ...
Well I would like to comment on further aspect of using if-else with exists.
It's best to avoid using if-else with exists. Why?
You need to make sure at least one record exists in your table
This method does not allow for concurrency (specially in insert, updates transactions, it could end u...
dezso was right, the PGPASSWORD environment variable is present when executing Tomcat from a single shell, but not when it's started as a service. The solution is to put the value in the process environment:
ProcessBuilder builder = new ProcessBuilder(
"C:/postgres9/bin/pg_dump.exe",

I executed this on my SQL Server:
EXEC sp_configure 'show advanced options', 1
And then executed RECONFIGURE. This presented me with the following error message:

PostgreSQL 9.2.2 on Windows 7 64-bit.
The setting log_statement in the postgresql.conf file specifies what statements to log (none, DDL, data-modifying, or all). To what extent does setting log_statement = 'all' degrade performance? I've read that this significantly reduces performance, but th...
Here is a question from Joey, which is his first post on DBA.SE (his user profile shows exactly one question and no answers so far). However, the first posts review list is empty (and today's listing shows zero reviews). Shouldn't this post show up in this list?
EDIT
Recently I experience the...
Back in October, dezso asked this question which is flagged as bug fixed. However, I'm still seeing the issue that a user's first post is not showing up in the first post review list. Here is an example:

According to my research, trygvis did review it: http://dba.stackexchange.com/review/first-posts/5569 and about 90 minutes before you asked this, give or take.
Additionally, let me show you how I got there :D
I know its something that should be avoided for performance reasons, but am trying to show a condition where it appears as a demo on how to make sure it does not appear.
However, I end up with a missing index warning, yet the optimizer chooses not to create a temporary index.
The query I am usi...
One way to get an index spool to appear naturally is to express the requirement using slightly different syntax:
SELECT DISTINCT
z.a
FROM dbo.t5 AS z
JOIN dbo.t4 AS y ON
y.a >= z.a AND y.a <= z.a
OPTION (LOOP JOIN, MAXDOP 1, FORCE ORDER);
This produces an execution plan like:
...0
I wonder if it is safe to run the Tablediff tool on a database fairly often?
Let's say every 15 or 30 minutes. Also, the Data in the DB is around 100 GB.
