Hi,

I am using ASKBOT 0.7.48 and Django 1.4. DB is postgres

I am unable to run migrations successfully. The process exits in middle of migration raising an unexpected error.

There was a related issue question - 10912 but i am not sure if this has been fixed for postgres backend too. Please help me resolve the issue.

I think you have some connection error with postgre server, the second about "forum_anonymousanswer" it's say it does not exist in your table, try to add this table (just new empty table).

@umang, can you describe steps to reproduce the issue?

Steps which results in the issue: 1) Take a new created DB in postgres 2) Run the syncdb and migrate command 3) Migration fails when it reaches the migration askbot:0013_add_response_count__to_user 4) The same when used with sqlite works just fine. (The problem is specific to postgres )
