When you start interactive bash, it runs .bashrc first and then it gives you an interactive prompt. Very handy to setup bash in the right way.
I'm trying to do the same with Postgres client (psql). I want to set some session configuration parameters before I run SQL statements interactively. Does psql let me do that?
The -c option and the -f option are the standard ways to run a pre-canned SQL statements, but the man page clearly states that those options are incompatible with the interactive mode.
psqlhas apsqlrcfile. See here psql under the section "Files" at bottom pf page. Or search forpsqlrcin the page.
