How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

sudo -u postgres -i psql -U ....becausesudo -u -i postgres psql -Uandsudo -ui postgres psql -U ...didn't work.psqlwanting to write to$HOME/.psql_historyis the cause of this issue. In support of this suspicion I would like to offer the output ofsudo -u postgres bash -c 'echo $HOME', which is/var/lib/postgresql; so writing to.psql_historyshould just work. No, for some reason,psqlseems to insist on doing achdirfirst to whatever the current working directory is, which for a non-interactivesudowill be the working directory of the invoker; hence the "could not change directory to/home/corey/scripts" output, which is unlikely to be someone's homedir.--set-homeflag tosudowill definitely print the homedir of thepostgresuser; but I will bet that, all other things considered equal,sudo --set-home -u postgres psqlwill still print the "could not change directory to ..." error.
