You can connect custom-built shell script with any database using unixODBC an implementation of the Open Database Connectivity standard and I will show you how to do this for SQLite and PostgreSQL databases.
Today, I will describe how to cause PostgreSQL clusters to reload their configuration files using four simple methods.
This blog post is an update to the earlier PostgreSQL entries in which I will show you how to use continuous Write Ahead Log archiving to take advantage of the point-in-time recovery.
I have already described a simple way to perform base PostgreSQL backup using file system utilities. Now I want to show you a different approach using pg_basebackup utility.
Today I want to show you how to perform base PostgreSQL backup using standard file system utilities. It is great example as it briefly describes basics required before moving to more advanced topics.
Sometimes I want to monitor and log particular PostgreSQL statements or execute other kinds of external action. I am using the notify mechanism and slightly modified sample application found in the database documentation to achieve this.
I wrote a simple shell script to pretty-print disk space used by PostgreSQL databases while examining database object size functions. You can benefit from this too by inspecting used SQL statements.
I often want to omit data from certain tables during PostgreSQL database backup. Today I will look into this and post my findings for further reference.
