I get the following error when updating Playa to V4.4.5
Unknown column 'parent_var_id' in 'exp_playa_relationships'
ALTER TABLE exp_playa_relationships ADD parent_is_draft INT(1) UNSIGNED NOT NULL DEFAULT 0 AFTER parent_var_id
Environment is MAMP, EE2.7.0.
This happens when clicking the playa link in the fieldtypes CP display. Oddly, the version is already at 4.4.5 when I do that, but maybe because I ran the module updates before - I was updating two other P&T addons at the same time - Matrix and Assets.
