Defect #1759

Migration from trac/postgresql fails with SQL error (probably important - postgres 8.3)
0%
Description
Migration from trac (with data in postgres database) ends with:
Migrating components...
Migrating milestones...
Migrating custom fields
Migrating tickets.rake aborted!
PGError: ERROR: operator does not exist: text = integer
LINE 1: ...CT * FROM "attachment" WHERE ("attachment".id = 1 AND (a...
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
: SELECT * FROM "attachment" WHERE ("attachment".id = 1 AND (attachment.type = 'ticket'))
The same SQL fails when issued from psql, to have it working one must quote this identifier - WHERE ("attachment".id = "1" ....)
PS Postgres 8.3 is restrictive on datatypes....

... and it seems this id is indeed expected to be textual. When I tried to workaround this by renaming the table attachment in trac database and recreating new one with id modified to be integer, I got:
Migrating components...
Migrating milestones...
Migrating custom fields
Migrating tickets..........................................................................
Migrating wiki.rake aborted!
PGError: ERROR: invalid input syntax for integer: "Reconfiguration"
: SELECT * FROM "attachment" WHERE ("attachment".id = E'Reconfiguration' AND (attachment.type = 'wiki'))
('Reconfiguration' is a name of some wiki page).

The first problem is indeed fixed, I succesfully migrated all tickets.
But it turned out, that the second problem is not related to my hacks, but still present. Here is what I am getting now:
Migrating components... Migrating milestones... Migrating custom fields Migrating tickets.......................................................................... Migrating wiki.rake aborted! PGError: ERROR: invalid input syntax for integer: "Reconfiguration" : SELECT DISTINCT attachment.* FROM attachment WHERE attachment.type = 'wiki' AND attachment.id = 'Reconfiguration' (See full trace by running task with --trace)
As I already said, 'Reconfiguration' is the name of some wiki page I had in trac.
(I don't really care as I didn't have any wiki attachments, so everything I need is already migrated. But a bug is a bug)
Note: my trac was fairly old so I can't guarantee whether their current db schema is identical.

I'll try to move a sqlite trac database to pgsql to debug this problem.

Hi Jean-Philippe,
are there any news on this or is this issue closeable? :-)
Best regards,
Daniel
