Database administration and management is required for any database on which there are continuous business transactions.  If databases across enterprises are not monitored and maintained, then such databases are vulnerable to disasters, which eventually brings downtime to missions-critical application and, of course, it will incur losses in the business. Data is now one of the key assets for running a business, globally. Hence, it is one of the major responsibilities of enterprises to invest in resources for database monitoring and management. There are many database management and monitoring tools available for proactive database monitoring.

How to Install pgAgent On windows

Taking regular SQL database backup is one of the most important responsibilities of a database administrator. By setting up automatic database backup we can get rid of the additional overhead of doing it manually, every day, week or month. When it comes to PostgreSQL running in any Unix distributions or in Windows, there are at least two ways to do it. Using the built in CronJobs/ CronTabs in case of  Linux, and Windows scheduled tasks in Windows . Using PostgreSQL’s own scheduling agent,  pgAgent . Often DBAs tends to rely on CronTabs or Scheduled tasked because of the ease of use it offers. But there are several advantages if you use pgAgent instead. Though it takes a little effort to install pgAgent, it is much better than Cron jobs or Scheduled tasks. Why use pgAgent over CronJob: Compared to CronTab, PgAgent has the following advantages:  You can have multiple steps for a job without having to resort to a batch script. You can have multiple sched...

How to find the server is whether standby (slave) or primary(master) in Postgresql replication ?

-
Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)

How to Get Table Size, Database Size, Indexes Size, schema Size, Tablespace Size, column Size in PostgreSQL Database

-
In this post, I am sharing few important function for finding the size of database, table and index in PostgreSQL. Finding object size in postgresql database is very important and common. Is it very useful to know the exact size occupied by the object at the tablespace. The object size in the following scripts is in GB. The scripts have been formatted to work very easily with PUTTY SQL Editor. 1. Checking table size excluding table dependency: SELECT pg_size_pretty(pg_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 238 MB (1 row) 2. Checking table size including table dependency: SELECT pg_size_pretty(pg_total_relation_size('mhrordhu_shk.mut_kharedi_audit')); pg_size_pretty ---------------- 268 MB (1 row) 3. Finding individual postgresql database size SELECT pg_size_pretty(pg_database_size('db_name')); 4. Finding individual table size for postgresql database -including dependency index: SELECT pg_size_pretty(pg_total_rel...
