Обсуждение: alternate psql file locations
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 andrew

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.... a. -- Aidan Van Dyk Create like a god, aidan@highrise.ca command like a king, http://www.highrise.ca/ work like a slave.

I might well not want $HOME reset. Here's a small patch that does what I think would suit me and Alvaro. cheers andrew

You could argue that that's a bug, but it's been that way for a long time. cheers andrew

So, do we want to fix this and honor $HOME? -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +

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 andrew
