| Selectivity | temporal_sel_internal (PlannerInfo *root, VariableStatData *vardata, Period *period, CachedOp cachedOp) |
| Returns an estimate of the selectivity of the search period and the operator for columns of temporal values. More... | |
| double | var_eq_const (VariableStatData *vardata, Oid operator, Datum constval, bool constisnull, bool varonleft, bool negate) |
| Equal selectivity for var = const case. More... | |
