Some AV software probably behaves fine.
Probably.
In case anyone is interested:
I have two development computers that run Postgres on Windows XP.
One with Avira the other with Sophos.
Neither has or had any problems installing or running Postgres
Regards

Recently, I try to introduce my friend to use PostgreSQL.
However, he first impression is that. PostgreSQL is much slower
compared to MySQL. He realize he has to wait for 7 seconds, to create
a tmp database.
Why on earth would anybody compare database

Why on earth would anybody compare database performance using a command that
is usually executed only once in the lifetime of a database?
It's like saying The car from manufacturer A is slower than the one from
manufacturer B, because it takes 1 second longer to

Dear postgresql experts,
I want to know if postgresql has facilities for getting the first and or

Suppose I have the following table:

I'm considering using the windows version PostgreSQL in the following
conditions:
at least 10 years of up time (with periodic power failures= 1 a year)
I don't think you can get 10 years of up time on a Windows Server.

My apologies. This isn't PG-specific, but since this is running on
PostgreSQL 8.4, maybe there are specific features which might help.
I have a tree structure in a table and it uses materialized paths to
allow me to find children quickly. However, I also need to

The version is 8.2.4, the platform is win32
Does someone know the reason/workaround ?

Hello everyone,
I have an OpenOffice dabatase that I'd like to convert to Postgres.
More specifically I need to replicate tables, not null constraints,
primary keys, foreign keys, autonumbers and data. There's a tool that
does this with Microsoft databses:

Thanks but I don't have text type in my table.
sysdb=# \d changelogtest
techdb=# INSERT INTO changelogtest (id, txid, txtime) values (5, 123, 'now')
except select id, txid, txtime
from changelogtest
where id=5;
'now' *is* a text type value

No I haven't. I'm using MySQL right now. But I want to learn more
about Postgresql's Hot Standby and see if it offers a better
replication solution.
Can anyone share their experience about Postgresql replication
performance impact? Thanks.

No
and without installing as a service?
Yes (simply run pg_ctl manually from the command line)
