unique key names are not escaped

one of our programmers created a table with a column called "iso_639-1", it replicates fine.
There's a uniqe key on that column caled "unq_iso_639-1", which causes londiste to crash when adding the table to the subscriber.

It seems you are using Skytools 2.1. This bug seems to be fixed in 3.x.

You could either move to skytools 3.x... :) or instead copy this file from master:

https://github.com/markokr/skytools/blob/master/python/skytools/dbstruct.py

it should be mostly compatible. If you confirm it works fine as-is (or with few fixes) then I can commit it to 2.1 branch too. But I really don't want to do any 2.1-specific fixing (and testing) myself.

Hi, thanks for your answer.

Correct.

I've worked around it by renaming the Unique Key.
If i find time to test the replacement file, i'll keep you posted.
Is there anything particular i should test?
I was thinking about removing, and adding colums with unique keys on them
(including the funny names) and replicating some data. Anything else that
is important?

Cheers,

Initial copy (or resync) will test the module. So pick or create tables with various functionality or weird naming and see if it works.
