pgcrypto does not work for this scenario as far as i know.
pgcrypto enables me to encrypt my data and let only a user with the
right password (or key or whatever) decrypt it, right? So if i run it in
a test environment without this password the application is broken.
I still want to use these table columns in my test environment but
instead of real email addresses i want addresses like
random_number@xxxxxxxxxxx.
You might be right that it is a good idea to additional encrypt this data.

I would store sensitive data encrypted in the database. Check the pgcrypto module.

Hi,
I am working on postgresql 9.1 and loving it!
Sometimes we need a full database dump to test some performance issues with real data.
Of course we don't like to have sensible data like bunches of e-mail addresses on our development machines as they are of no interest for developers and should be kept secure.
So we need an anonymized database dump. I thought about a few ways to achieve this.
1. Best solution would be a special db user and some rules which fire on reading some tables and replace privacy data with some random data. Now doing a dump as this special user doesn't even copy the sensible data at all. The user just has a different view on this database even when he calls pg_dump.
But as rules are not fired on COPY it can't work, right?
2. The other solution I can think of is something like
pg_dump | sed> pgdump_anon
where 'sed' does a lot of magical replace operations on the content of the dump. I don't think this is going to work reliable.
3. More reliable would be to dump the database, restore it on a different server, run some sql script which randomize some data, and dump it again. hmm, seems to be the only reliable way so far. But it is no fun when dumping and restoring takes an hour.
Does anybody has a better idea how to achieve an anonymized database dump?
