Add missing check_collation_set call to bpcharne().
We should throw an error for indeterminate collation, but bpcharne()
was missing that logic, resulting in a much less user-friendly error
(either an assertion failure or "cache lookup failed for collation 0").
Per report from Manuel Rigger. Back-patch to v12 where the mistake
came in, evidently in commit 5e1963fb7. (Before non-deterministic
collations, this function wasn't collation sensitive.)
