Обсуждение: pgadmin is changing pgpass.conf
Hi All, I have been having a few problems with my password file recently, causing my scheduled pg_dump to fail. The problem is that the pgpass.conf file keeps changing. Eventually I narrowed it down to using pgadmin. Every time I start pgadmin, it changes the contents of my pgpass file, even though I do not store my password in pgadmin. This only seems to have become a problem since installing 8.4 and associated version of pgadmin. Is this the desired behaviour or is it a bug? Howard Cole www.selestial.com

It's the desired behaviour, and is described in the pgAdmin docs. As I remember there was also a discussion (on the pgadmin-support list I think) when this feature was added, on the merits or otherwise of storing passwords in plain text on disk.

Unfortunately this behaviour has the side effect of deleting passwords that I have set up in the file manually for other applications (namely the backup), which runs under the same user account. I guess I'll just have to come up with an alternative. Howard. www.selestial.com

I guess I'll just have to come up with an alternative. Hi Howard, I'm afraid that's about the size of it. It's probably a good idea to have a separate account for executing the backup in any case.

There are originally two entries in pgpass.conf - one for server localhost and one for server 127.0.0.1 - the reasoning behind this is that when the backup runs as a scheduled task it sometimes seems to prefer one format to the other. However, when I open PGAdmin, one of the entries disappears. Perhaps it resolves the address and thinks they are the same entries? Anyway, the problem was resolved in the script that executes pg_dump, forcing it to use localhost or 127.0.0.1 using the -h option. As long as the -h ties in with what pgadmin writes to pgpass, there are no authentication problems. Howard Cole www.selestial.com

I think you should file this as a pgadmin bug -- see the pgadmin lists for that. -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support
