Is all data in the database? and what is the master connection?

[Kevin Bailey <..hidden..>]

Hi,

We're looking to implement LedgerSMB for our accounts.  I'd like to set 
up a couple of separate training copies which should be copies of the 
live accounts.

I'll have LS installed via Debian packaging - and I've tested installing 
on a VM.

One thing I like is that the databases seem self contained - the the 
SQL-Ledger way of storing users in text files seemed to be not very 
portable.

My question is - are all the details about a set of accounts stored in a 
single database - what about templates and any image files used in those 
templates?  I.e. how easy is it to create an exact copy of a set of 
accounts - is it just a question of copying the database?

And...

What is the master connection to the database?  Is this normally the 
user postgres or a new similar user set up.  I had some issues with this 
before and would prefer not to have to set a password for the user 
postgres - I suppose I should set up a new user which works in the same 
way as the postgres user.

Thanks,

Kevin Bailey
