Обсуждение: BUG #2690: GRANT does not allow periods in database or schema names

The following bug has been logged online:

Bug reference:      2690
Logged by:          Nick Johnson
Email address:      pgsql@spatula.net
PostgreSQL version: 8.1.1
Operating system:   FreeBSD 6.1
Description:        GRANT does not allow periods in database or schema names
Details:

Though you can create a database with a period in the name (e.g.,
"example.com"), you cannot issue a GRANT on that database name from the
command line.

pgsql=# GRANT ALL ON DATABASE example.com TO someuser;
ERROR:  syntax error at or near "." at character 30
LINE 1: GRANT ALL ON DATABASE example.com TO someuser;

The same syntax works okay for databases without a period in the name.

Either GRANT should work on any database name that works when creating a
database, or CREATE should disallow the same things that GRANT disallows.

Sure you can.  Just quote the name:

GRANT ALL ON DATABASE "example.com" TO someuser;

You are making the faulty assumption that example.com and "example.com"
are the same thing.

You need some double quotes:

This is by no means unique to GRANT, nor to database names.
