\nWorking with AWS RDS isn’t always the easiest. That’s the limitations that come with hosted solutions. \/shrugs\/<\/p>\n

For example, you can’t change master username once an instance has been spawned, not even on an instance restored from a snapshot.<\/p>\n

But I did figure out how to change a Postgres RDS instance’s database name. To do this, we’ll need terminal connection to the database:<\/p>\n

<\/div><\/td>
$ psql -U<\/span> james_holden -h<\/span> my-database-identifier.abc123.us-west-2<\/span>.rds.amazonaws.com -d<\/span> donnager
\n$ password for<\/span> james_holden: # provide your db password here<\/span><\/div><\/td><\/tr><\/tbody><\/table><\/div>\n

At this point, if you attempted to change the database name, Postgres will complain immediately:<\/p>\n

<\/div><\/td>
donnager<\/span>=><\/span> ALTER DATABASE donnager RENAME TO rocinate;
\ndonnager<\/span>=><\/span> ERROR:  current database cannot be renamed<\/div><\/td><\/tr><\/tbody><\/table><\/div>\n

However, if you get out of the connected db, switch to the standard “postgres” db, it’s all fair game:<\/p>\n
