Обсуждение: Re: [BUGS] createdb comments
[I've changed the list to -general from -bugs. I hope that's acceptable] Thanks Bruce, If I'd realised createdb was that simple I'd have done it myself. However, I think I was locked into the idea that the SQL command should work as well. I'm afraid I don't know the standard but from the command I would assume that the COMMENT ON DATABASE was intended to work on any database from any database. Is that incorrect, possibly because of security concerns? On Tue, 11 Jun 2002, Bruce Momjian wrote: > > The following patch [somehow lost by pine in my reply] fixes the > problem.

Is that incorrect, possibly because of security concerns? No, it can't because pg_description is per-database, while pg_database is global to all databases. No way to handle this because we can't update every pg_description in every database. We could update just template1's pg_description, but only the super-user can do that. What we do is to just update the datbase description stored in the current database. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
