Hi all,
as I did not find the answer in the documentation: Which background process is
actually doing the writes/flushes to the WAL? In the docs

Hi all,
currently I am preparing my session (PostgreSQL upgrade best practices) for the
Swiss PGDay 2017 (http://www.pgday.ch/2017/). What I plan to come up with is:
- Support policy
- Release notes
- Why it is important to upgrade (or at least to patch to the latest minor
release)

Hi,
PostgreSQL 9.6.2 on CentOS 7.3 x64.
This is my data set:

drop table if exists ids;
create table users ( user_id int

);
with generator as
( select a.*
from generate_series (1,300) a
order by random()
)
insert into users ( use

Hi all,
I have a PostgreSQL 9.5.4 and a PostgreSQL 9.6.1 instance installed on the same
host. I dump the 9.5.4 instance with:
pg_dump -h localhost -p 5438 -C -c -F d -j 2 -f /var/tmp/exp/ test
.. which runs fine. I get the output as expected:
postgres@pgbox:/home/postgres/ [PG954] ls /var/t

The description on the website is wrong:

Shoud be 9.5.3, shouldn't it?

Hi,
if I'd need to implement/replace Oracle Text
(ww.oracle.com/technetwork/testcontent/index-098492.html). What choices do I
have in PostgreSQL (9.5+) ?

Hi
I have a question about memory management in PostgreSQL. I understand the
default on Linux usually is "posix" which creates files in /dev/shm. With the
default settings of 128MB for shared_buffers this is the result:
ls -la /dev/shm
total 4
