Hi Dave,

I think that you brought the 'cid' issue to my attention before. I am
willing to let 'cid' be changed to 'cat_id' or 'category_id', in order
to fix this problem. As far as I'm concerned, if a particular field
name is already 'taken' by a core module, then a contrib module (such
as category) should respect that.

Having said that, I believe there are examples of field name conflicts
even within core. For example, 'fid' is used both as 'file ID' (by the
'files' table), and as 'field ID' (by the 'profile_fields' table).
IMHO, the most sensible route to take is to accept that field name
conflicts are inevitable, and to make sure that db_rewrite_sql is able
to handle them (and to improve db_rewrite_sql if it can't handle
