After noticing that some duplicate Davmail icons were appearing in my system tray after some uptime, I did a bit of investigation, and eventually found out that this was caused by the display scaling. ![]() The files belonging to this database system will be owned by user "postgres". Everything works as expected, I have it set up to start at logon and when I turn on the computer there is one davmail icon in the system tray. usr/lib/postgresql/11/bin/initdb -D /var/lib/postgresql/11/standby1 -auth-local peer -auth-host md5 Nothing prevents us from doing a similar wrapper on other Linux distros also.Ĭreating new PostgreSQL cluster 11/standby1. In this blog, I want to show how this can be done on Ubuntu/Debian Linux because all necessary wrapper scripts already exist on those distros as part of postgres-common package which gets installed by default with every PostgreSQL installation. So everything is getting converged to systemd in the new world. To my surprise, some of the MySQL packages started removing mysqld_multi from the bundle and started moving towards systemd as the way to manage multiple instances. During this time, systemd started becoming a standard among Linux distros and every Linux package started relying on it for service management. In short, the answer is that the PostgreSQL community manages it using wrapper scripts and the Linux service manager. In a discussion a few months back, one of my friends asked how PostgreSQL manages multiple instances and I agreed to write on that as it will be useful for anyone who looks for a similar setup. Even though this is not a core feature in MySQL, but rather a wrapper, I understand that it is something widely used and my colleague Fernando blogged about it. MySQL historically ships mysqld_multi to manage multiple instances of MySQL on a server. Most of the time, I keep addressing Oracle DBAs who are looking for similar features or setup in PostgreSQL, but this time it is for MySQL DBA. It is a human tendency to look at any new technology and compare it with a world they are familiar with. That way, I can hook up the input signals of the alg_unit blocks generated "later" to the output signals of the alg_unit blocks generated "earlier".Those DBAs who are experts in one database system look for other database systems to have âsimilar featuresâ. I need a way to refer to previously instantiated alg_unit blocks. generateįor (i=0 i ![]()
