Hello,
The current definition of the extra_hdrs is:
    <column>
        <name>extra_hdrs</name>
        <type>text</type>
        <default/>
        <description>Extra headers that must be restored</description>
    </column>
which results in
extra_hdrs TEXT DEFAULT '' NOT NULL
in mysql and postgres. This has a default value. Do you think it should have both a default and be allowed to be NULL?

Regards,
Hugh

Hello,

looking at changes in the database structure from 3.2 to 3.3, I noticed the columns in active_watchers/rls_watches that have no default value and cannot be NULL.

The usual issue with this kind of upgrades is that existing rows have to be removed. active_watchers is with temporary records, and I guess that is the same with rls_watchers. No persistent data is to be lost, right?

Another one is extra_hdrs in silo table. I think it should be allowed to be NULL or default '' (empty string), so stored messages will not be lost - the check over the code showed inserting '' if no extra headers are present at message storage time.

Cheers,
Daniel
