Login problems - again.

[Richard <..hidden..>]

Hi,

so I've got the dbase restored, and via pgpadmin it looks like the data 
is there, browsing through the tables.

Unfortunately, after the 'user details' entry at the end of the restore 
process, I can now no longer log into LSMB. I can log in to Set Up no 
problem.  So it looks like, for whatever reason, I don't have a user for 
LSMB, i.e. for login.pl.

How can I create one without being able to access LSMB - I've spent all 
afternoon googling and trying stuff, but to no avail - not helped by 
most advice bring trying some Postgres command but not telling me 
whether I should be an ordinary user, at the postgres prompt or pqsl 
prompt; and then getting syntax errors anyway ;-)

Can someone *please* tell me how to, or point me to some where that 
really explains how to, create a user that I can log in with when I 
cannot log in via login.pl - I'm seriously frustrated after 4 days 
trying to restore from a back-up, and my customer has made it very clear 
I'm not getting paid for most of my time.

Cheers
Richard
