Re: database restore problem

Hi Chris. It seems you preformed a data-only backup as the log provided doesn't show DDL sentences.<br />Having done so
couldface you with two problems:<br />1. The destination database schema is different than the one where you performed
thebackup. The error reported on table alert_request seems to confirm this.<br /> 2. You probably already have data on
thedestination database which triggers the unique key contraints.<br /><br />If this proves to be the case you should
checkyour schema is identical to the original one. Then truncate all tables before restoring data.<br /><br

Ina nutshell, I'm having trouble restoring my backup of a database. Some of the data was exported and put in
spreadsheets,where it is safely stored, but some was not, and I would like to get that data back.<br /><br /> Now the
details:I had a database that I was using to store data from a radio reciever. It was basically installed and set up by
otherpeople, and now I've inherited it and it's my problem. The data was radio signal strength data from radio collared
mice(I'm a biologist). All went well, and by the end of the summer I had a nice pile of data. <br /><br /> We decided
tomove the whole system to another computer, so we created a backup of the database, using the "backup" function in
PGAdmin.I just used the dropdown menu and foolishly assumed that if I told it to backup the database that it would, and
everythingwould be fine when I tried to open the file. I didn't pay much attention to the settings (because I'm a
newbie),and probably just used the defaults. Then we installed PGAdmin and PostgreSQL (same versions, 8.2.4 and 1.6.3
respectively)on the new computer, and we're trying to restore the database from the backup file. The original computer
andthe original database have since died, so all that is left of the database is this backup file.<br /><br /> This is
theerror message I get: <br /><br /><div style="margin: 5px 20px 20px;"><div style="margin-bottom:
