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_num...@example.org.

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

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?
