Fix the volatility marking of textanycat() and anytextcat(): they were marked
immutable, but that is wrong in general because the cast from the polymorphicargument to text could be stable or even volatile. Mark them volatile forsafety. In the typical case where the cast isn't volatile, the planner willdeduce the correct expression volatility after inlining the function, soperformance is not lost. The just-committed fix in CREATE INDEX also ensuresthis won't break any indexing cases that ought to be allowed.Per discussion, I'm not bumping catversion for this change, as it doesn'tseem critical enough to force an initdb on beta testers.
