The least comment in the issue thread says it is fixed after deleting
the pyc. Is that not correct?

Yes - just a clean version of web2py pulled by Hg from Google code.
Did you set a sequence_name

No (not even sure what sequence_name is!) - I tried another app of
my
own
and get the same result.

I am getting the same error as reported by Carlos and cannot fix it.
I have just set up a new server (Ubuntu 10.04 - postgres 8.4, Python
2.6.5)
and have web2py trunk up and running fine. I have an unmodified
'welcome'
app which runs perfectly with sqlite.
I then delete all the files in databases, cache and sessions. Next I
create a postgresql database and grant permissions to the appropriate
user.
I have double checked this and the user can create tables on the
database.
Next change the connection details in the welcome app db.py to:
db = DAL('postgres://myuser:mypasswordlocalhost/mydb')
Then visit the URL and I get the ticket below.
Any help gratefully appreciated. (I had this running fine on a previous
server)

Should I worry about this problem appearing again (in my local machine or in a production environment)?. I have seen this several times when I change definitions of tables using Postgresql as backend. What I normally do in such sitations is to export the database table to a csv-file through Web2py or if that is not possible using either the commandline or PGAdminIII, drop the table and remove the table's entry in web2py/applications/myapp/databases. Web2py will then recreate the table and you can import the csv-file. If the latter was created with outside web2py, you will have to edit the column headers before importing it. I am not sure whether this is good practice but this has saved me some frustrations.
