ALTER TABLE {$NAMESPACE}_phriction.phriction_document
  ADD editedEpoch INT UNSIGNED NOT NULL;
Move Phriction internal document/content references from IDs to PHIDs Summary: Ref T13077. This is mostly just a small cleanup change, even though the actual change is large. We currently reference content and document objects from one another with `contentID` and `documentID`, but this means that `contentID` must be nullable. Switching to PHIDs allows the column to be non-nullable. This also supports reorienting some current and future transactions around PHIDs, which is preferable for the API. In particular, I'm adding a "publish version X" transaction soon, and would rather callers pass a PHID than an ID or version number, since this will make the API more consistent and powerful. Today, `contentID` gets used as a cheaty way to order documents by (content) edit time. Since PHIDs aren't orderable and stuff is going to become actually-revertible soon, replace this with an epoch timestamp. Test Plan: - Created, edited, moved, retitled, and deleted Phriction documents. - Grepped for `documentID` and `contentID`. - This probably breaks //something// but I'll be in this code for a bit and am likely to catch whatever breaks.
