That problem seems easy to address by adding a newline into the default prompt. Something like this: \set PROMPT1 '%n@%~%R%\n# ' I myself use: \set PROMPT1 '%[%033[1m%]%M %n@%/:%>-%p%R%[%033[0m%]%\n> '

On the whole, I think we'd get more complaints about the default prompt having more-or-less doubled in length than we'd get kudos about this being a great usability improvement. Prompt space is expensive and precious, at least for people who aren't in the habit of working in very wide windows. regards, tom lane

Here’s a patch for this.- Kori session-user-prompt.patch Description: Binary data On May 27, 2023, at 8:52 AM, Andrew Dunstan wrote: I don't recall if this has come up before. I'm sometimes mildly annoyed when I get on a new system and find the username missing in my psql prompt. Or if a customer shows me a screen and I have to ask "which user is this".

My usual .psqlrc has \set PROMPT1 '%n@%~%R%x%# 'So my suggestion is that we prepend '%n@' to the default psql PROMPT1 (and maybe PROMPT2).I realize it's not exactly earth-shattering, but I think it's a bit more user-friendly.(Would be a good beginner project, the code change would be tiny but there are lots of docs / examples that we might want to change if we did it.) cheers andrew -- Andrew Dunstan EDB: https://www.enterprisedb.com
