[1.9] Adding db fields - will it break updates?

[6502programmer]

If I add a field called date_create to ttrss_filters2_rules defaulting to CURRENT_DATE (I'm using PGSQL), will it cause upgrades/updates to lose their marbles, or will it ignore the field?

The scenario is I want to use rules, but my rules would have a lifetime of only a few weeks, then I should never see them hit again. I don't want to pile up thousands of rules, so I would use the datestamp to prune ones that are older than a month or so. I have a function to insert to ttrss_filters2_rules with the proper filter_id, filter_type, and feed_id, as well as my reg_exp to use as my filter basis.

Unless I add an identically named field, no.
