Package: trac
Version: 0.10.4-2
Severity: serious
Today I upgraded PostgreSQL to 8.3.
This version more strictly checks types of columns and parameters.
After this upgrade any operations in Trac that try to access Subversion
repository (Timeline, Browse Source) fails.
For example "Browse source" results in following web page:

ProgrammingError:
operator does not exist: text = integer
LINE 1: SELECT time,author,message FROM revision WHERE rev=238
^
HINT: No operator matches the given name and argument type(s).
You might need to add explicit type casts.
Problem lies in table revision, column rev; this column has type text,
which conflicts with number given to query as parameter.
Changing type of this column to integer helps.
It looks like there is no other column referencing revisions.rev,
so this can be done without problem.
Following SQL commands allow for fixing exisitng Trac database;
after those, Trac works again.
alter table revision add column r integer;
update revision set r = rev::int;
alter table revision drop column rev;
alter table revision rename column r to rev;
alter table revision alter column rev set not null;
alter table revision add primary key (rev);
I set severity for serious because this error makes Trac only partially
usable, although it does not cause data loss.
