Default PostgresSQL on a networked drive with multiple users

Thanks Craig for making me look like an idiot. I feel bad now.

When I posted I suspected that what you have just replied with was the
case.

I have some leaning to do on this.

That wasn't my intent, so I'm sorry for making you feel bad about it. I
was just trying to stress the importance of only ever having one pg
instance using a data directory. If you're used to shared-access systems
it's a natural question, and the documentation:

http://www.postgresql.org/docs/8.3/s...g-cluster.html

doesn't explicitly spell out that it's a bad idea to have multiple Pg
servers accessing a database cluster.

I'm sure that wasn't Craig's intent. I'd hazard a guess that you've been
using Access or a similar single-file-based DB where the you simply
point the front-end at the data file, and the front-end looks after
locking and concurrency (I think - I may be way off on this). PostgreSQL
and other "heavyweight" DBMSs require a different mind-set - think of
the server as a black box at which you fire off your SQL and get back
the results.

HTH,

Ray.

You don't look like an idiot, you look like someone who has just learned
something. If we don't learn from our mistakes, then we are idiots...
