psql

问题 I would like to paste 123 456 789 into psql and to store multi-line string in some variable (ie. :str ) for later use. Is that possible? Now I'm getting unterminated quoted string error. 回答1: A little clunky, but in version 9.3 and up, you can do it with \gset in conjunction with a dollar-quoted literal: SELECT $$123 456 789$$ AS str \gset 来源： https://stackoverflow.com/questions/31454108/defining-multi-line-strings-in-psql

问题 My postgres windows client, upon receiving a query with many results, only shows some of them initially, showing -- More -- at the bottom and making you hit "enter" to show each new result line. This is cumbersome and silly. What can I do to make it show me absolutely every result from the start? 回答1: Assuming you mean psql with "my postgres windows client", you can turn off the use of the pager using the \pset command: \pset pager off If you want to permanently turn the pager off, add that

问题 I am using the postgresql (9.4) interactive terminal psql on Windows 8.1 (64 bit). After installing and creating a database and table and inserting data into a row I want to view the data. However, when I type SELECT * FROM my_table; I get an error: 'more' is not recognized as an internal or external command, operable program or batch file. After adding "C:\Windows\System32;" to my path variable, more works in Powershell (e.g. more hello.txt) but still not in psql. What else do I need to do

问题 If I create the pg_cron extension in a docker-entrypoint-initdb.d/init.sql file, the docker image fails to run and docker logs <id> just says "No such container."
