无法重命名PostgreSQL数据库

Question

I'm using PostgreSql 9.2. Trying to do

ALTER DATABASE 3_8_dev_test6 RENAME TO 3_8_dev_test

but get:

ERROR:  syntax error at or near "3"
LINE 1: ALTER DATABASE 3_8_dev_test6 RENAME TO 3_8_dev_test

So what's wrong?

Answer 1

If the name really starts with a number then use double quotes

ALTER DATABASE "3_8_dev_test6" RENAME TO "3_8_dev_test"

But then you will have to match the case also

Answer 2

Postgres assumes you're going to enter a number in this case so if you want to have numbers in the beginning of a name, use quotes :)

In this case:

ALTER DATABASE "3_8_dev_test6" RENAME "TO 3_8_dev_test";
