DO NOT PERFORM UNTIL 1.23wmf19 in on enwiki - expected March 25, 2014

Short description:

Drop the tree_orig_create_time column which turns out to be redundant. I'm not sure what the best way to track this is, but basically I merged the required pre-patch today. It will go to phase0 next thursday and phase2 the thursday after that(March 25, 2014). This be column must not be dropped until then but filing a bug now so it doesn't get lost.

Which wikis are affected:

flowdb on the non-wiki extension1db

Which tables:

flow_tree_revision

What is the change to those tables:

ALTER TABLE /*_*/flow_tree_revision
DROP COLUMN tree_orig_create_time;
