#3677 closed defect (fixed)
Database operations fail with PostgreSQL 8.3
| Reported by: | Owned by: | Steffen Hoffmann | |
|---|---|---|---|
| Priority: | normal | Component: | TagsPlugin |
| Severity: | normal | Keywords: | postgresql text cast |
| Cc: | Ryan J Ollos, Michael Renzmann | Trac Release: | 0.11 |
Description
As of PostgreSQL, many automatic casts to text were removed. See the release notes. A symptom is the following error I received:
ProgrammingError: operator does not exist: text = integer
LINE 1: DELETE FROM tags WHERE tagspace=E'screenshots' AND name=3
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
Traceback:

Patch to use to_unicode for any instance of the tag "name" attribute.

Hmm, has this problem been fixed meanwhile? I'm runnung v0.6 of the plugin along with Trac 0.11.6 and PostgreSQL 8.3.9 on Debian Lenny, and I didn't spot any issues related to the tags plugin.
Can you please confirm that it still exists?
comment:3 Changed 14 years ago by
I am also using TagsPlugin with 0.12-stable and PostgreSQL 8.4 and do not have any issues. Closing as I believe this is fixed in the trunk branch of tags. I think this issue can be closed.

I'll do some further checking, but converting to unicode object on first read of tag name would be better than multiple times further down in the process as suggested here.

As I see now, this ticket's proposed changes have been applied together with other API changes in [13429].
Note: See
TracTickets for help on using
tickets.
The first sentence should read:
"As of PostgreSQL 8.3, many automatic casts to text were removed."
