[SOLVED] How to rename PostgreSQL database using psql CLI?

[nelsonic]

At present I have a Postgres database on my localhost that I don't want to DROP,
but I want to start again from scratch for dwyl/auth#174 ...
So I want to rename the auth_dev database so I can re-use that name. 💭

This should be a 1 minute task. But I want to record it somewhere in case I need to do it again.

Indeed this was 1 min of googling to refresh memory ...
The ALTER command is what we're looking for: https://www.postgresql.org/docs/current/sql-alterdatabase.html

In a terminal window on Mac/Linux type: psql to start the Postgres CLI.

List the databases: \l (that's a backslash and lowercase "L"):

Rename:

The command to alter the name of the database is:

ALTER DATABASE db RENAME TO newdb;

In my case it was:

ALTER DATABASE auth_dev RENAME TO auth_dev_archive;

Looks like it worked:
