491954 - Views should select exact columns

Status: VERIFIED FIXED

(Toolkit :: Places, defect)

Description

[Shawn Wilsher :sdwilsh]

Our views should select exact columns so we don't kill our ability to downgrade between versions.  This *must* be fixed before we ship 1.9.1 or we'll stick ourselves into a nasty nasty hole.

well, really we should avoid "SELECT *" everywhere we UNION.
Just to be safe for future changes i've removed all SELECT * FROM real_table, and replaced with COLUMNS macros.
Plus moved indexes to their own file.

This isn't needed since we don't use temporary tables here.  Please don't add complexity like this unless we have to.

this should either block or have approval, we need this change to allow any future schema upgrade.

Marking verified fixed based on checkins into trunk and 1.9.1 branch. There is no way for me to check this manually.
