  25. Rename pg_constraint.conwithoutoverlaps to conperiod

  26. Fix comment on gist_stratnum_btree

  27. Add missing TAP test name

  28. Improve error handling of HMAC computations

  29. Rename functions to avoid future conflicts

in GetOperatorFromWellKnownStrategy:
*strat = GistTranslateStratnum(opclass, instrat);
if (*strat == InvalidStrategy)
{
HeapTuple tuple;
tuple = SearchSysCache1(CLAOID, ObjectIdGetDatum(opclass));
if (!HeapTupleIsValid(tuple))
elog(ERROR, "cache lookup failed for operator class %u", opclass);
ereport(ERROR,
errcode(ERRCODE_UNDEFINED_OBJECT),
errmsg(errstr, format_type_be(opcintype)),
errdetail("Could not translate strategy number %d for operator class
\"%s\" for access method \"%s\".",
  instrat, NameStr(((Form_pg_opclass) GETSTRUCT(tuple))->opcname), "gist"));
ReleaseSysCache(tuple);
}

last `ReleaseSysCache(tuple);` is unreachable?

the comment seems not clear to me. Here is my understanding about it:
period_contained_by_oper is the operator where a single period/range
contained by a single period/range.
agged_period_contained_by_oper is the operator oid where a period
contained by a bound of periods
period_referenced_agg_proc is the oprcode of the agged_period_contained_by_oper.
period_referenced_agg_rettype is the function
period_referenced_agg_proc returning data type.
