!!!Postgres hints:
!!IDENT authentication failed for user
Postgresql under [Debian] by default uses [IDENT] authentication to authenticate a user connecting to the database. In english this means that you can only connect to the database with the same username as your unix login. This can be edited in /etc/postgres/pg_hba.conf (Host Based Authentication) by changing "ident sameuser" with "trust" to let anyone connect to the database with any username without a password, or "crypt" etc.. The file is well commented, refer to it for more details.

+!!Upgrading from 7.2 to 7.3
+
+A couple of minor "gotchas". As above, check your pg_hba.conf file. Previously "password" authentication covered all forms of stored password. Now it is strict. If you are using md5 passwords, it MUST be md5.
+Also, in SQL-land, LIMIT used to be fairly forgiving about its arguments. It would accept MySQL format without blinking. Now it's strict - this caught me out on a basic weblog script I use which had been ported from MySQL.
+Finally, if you are a [Debian] user, don't believe the instructions in the update README!
+psql -e <dumpfile will NOT restore your database...you need to do psql template1 -e <dumpfile.
