Several plugins report "OperationalError: table wiki has no column named ipnr" on upgrade

[matthias@…]

With Trac 1.3.2 I tried out several plugins for time estimation / tracking. After activation of the plugin in the admin section of trac, it requires me to run trac-admin upgrade. The upgrade fails with the error message:

OperationalError: table wiki has no column named ipnr

I checked the db schema of the project and the column really doesn't exist:

trac /srv/trac/projekt1/db >sqlite3 trac.db
SQLite version 3.25.1 2018-09-18 20:20:44
Enter ".help" for usage hints.
sqlite> .schema wiki
CREATE TABLE wiki (
    name text,
    version integer,
    time integer,
    author text,
    text text,
    comment text,
    readonly integer,
    UNIQUE (name,version)
);
CREATE INDEX wiki_time_idx ON wiki (time);
sqlite> 

Beeing new to trac, I'd like to ask if:

a) This column was part of a former trac version and was dropped for the devel branch? In this case - what was the purpose of this column?

b) This column was never part of the trac db scheme and maybe was added by another plugin?

c) The column should be there, but my installation is wrong?

Please ask on the MailingList for support questions.

Also, the ipnr columns have been removed in milestone:1.3.1 (#9612).

The 1.3.x is development version for committers, plugin authors, early testers…. If you will use Trac under production, you should use 1.2.x or 1.0.x.

It would be helpful if you filed reports for the incompatible plugins to the plugin's issue tracker.
