  1. alternate psql file locations

    Andrew Dunstan <andrew@dunslane.net> — 2011-12-31T15:52:02Z

    It's not a big thing, but I just found myself in a shared environment 
    wanting to be able to set alternative locations for the psql startup 
    file and history. I know there's the HISTFILE variable, but I can't 
    easily set that automatically unless I can at least have my own .psqlrc. 
    ISTM it should be a fairly simple thing to provide these, via 
    environment variables. Is there general interest in such a thing?
    
    cheers

    Generally when I've wanted these things, I just make a new "$HOME" in
    my shared user home dir:
    
    export HOME=$HOME/aidan
    
    It's worked for things I've wanted, I haven't tried it for psql stuff....

    Yeah, but it's a bit hacky. I might well not want $HOME reset. Here's a 
    small patch that does what I think would suit me and Alvaro.

    Incidentally, this actually doesn't work anyway. psql gets the home path 
    from getpwuid() and ignores $HOME. You could argue that that's a bug, 
    but it's been that way for a long time.

    So, do we want to fix this and honor $HOME?

    Not really. Mangling it is a nasty hack anyway. Meanwhile see the 
    subsequent 9.2 feature (described thus in the release notes):
    
      *
    
        Provide environment variable overrides for psql history and startup
        file locations (Andrew Dunstan)
    
        Specifically, PSQL_HISTORY and PSQLRC determine these file names if set.
    
    cheers
