[COMMITTERS] pgsql: Fix regular-expression compiler to handle loops of constraint ar

2015-10-16 Thread Tom Lane
Fix regular-expression compiler to handle loops of constraint arcs. It's possible to construct regular expressions that contain loops of constraint arcs (that is, ^ $ AHEAD BEHIND or LACON arcs). There's no use in fully traversing such a loop at execution, since you'd just end up in the same NFA
