How to set 'timing on' permanently in PostgreSQL? I work with PostgreSQL in the command line interface. I would like to activate a \timing command permanently for every database in the cluster so every time I connect to a database - this parameter is on.
I searched in postgresql.conf file, but I haven't found anything like what I want to switch on.

My PostgreSQL is 9.5.4 on x86_64 Ubuntu 16.04.2.
\timing is specific to the client psql, not to the database server. You need to put that into the configuration file for psql which is ~/.psqlrc

See the manual for details: https://www.postgresql.org/docs/current/static/app-psql.html#AEN100589


  psql attempts to read and execute commands from the system-wide startup file (psqlrc) and then the user's personal startup file (~/.psqlrc), after connecting to the database but before accepting normal commands
