How To Send E-Mail From PostgreSQL

Hi ,

If you want to send E-Mails from PostgreSQL, then use the below Python 3.2 Script as below. I have used ActivePython 3.2 with PostgreSQL 9.1 for sending E-Mails from PostgreSQL.

If you want to configure the Python 3.2 with PostgreSQL 9.1 then, please refer the below steps.

Once, your Python 3.2 successful then follow the below steps to send an e-mail.

Step 1

postgres=# CREATE OR REPLACE FUNCTION public.send_email(_from Text,_password Text,smtp Text,port INT,receiver text, subject text, send_message text) RETURNS TEXT  LANGUAGE plpython3u
AS $function$

import smtplib
sender = _from
receivers = receiver
message = ("From: %s\nTo: %s\nSubject: %s\n\n %s"
 % (_from,receiver,subject,send_message))


  smtpObj = smtplib.SMTP(smtp,port)
  smtpObj.login(_from, _password)
  smtpObj.sendmail(sender, receivers,message)
  print ('Successfully sent email')
except SMTPException…

Pgpool Configuration & Failback

I would like to share the pgpool configuration, and it's failback mechanism in this post.

Hope it will be helpful to you in creating pgpool and it's failback setup.

Pgpool Installation & Configuration

1. Download the pgpool from below link(Latest version is 3.2.1).

2. Untart the pgpool-II-3.2.1.tar.gz and goto pgpool-II-3.2.1 directory.

3. Install the pgpool by executing the below commands:

./configure ­­prefix=/opt/PostgreSQL92/ ­­--with­-pgsql­-includedir=/opt/PostgreSQL92/include/ --with­-pgsql­-libdir=/opt/PostgreSQL92/lib/ make make install 4. You can see the pgpool files in /opt/PostgreSQL92/bin location.

pgBucket - A new concurrent job scheduler

Hi All,

I'm so excited to announce about my first contribution tool for postgresql. I have been working with PostgreSQL from 2011 and I'm really impressed with such a nice database.

I started few projects in last 2 years like pgHawk[A beautiful report generator for Openwatch] , pgOwlt [CUI monitoring. It is still under development, incase you are interested to see what it is, attaching the image here for you ],

pgBucket [Which I'm gonna talk about] and learned a lot and lot about PostgreSQL/Linux internals.

Using pgBucket we can schedule jobs easily and we can also maintain them using it's CLI options. We can update/insert/delete jobs at online. And here is its architecture which gives you a basic idea about how it works.

Yeah, I know there are other good job schedulers available for PostgreSQL. I haven't tested them and not comparing them with this, as I implemented it in my way.
Features are: OS/DB jobsCron style sytaxOnline job modificationsRequired cli options
