Functions | |
| bool | func_needs_index (Oid funcid, const IndexableFunction *idxfns, IndexableFunction *result) |
| Is the function calling the support function one of those we will enhance with index ops? If so, copy the metadata for the function into idxfn and return true. More... | |
| static FuncExpr * | makeExpandExpr (Node *arg, Node *radiusarg, Oid argoid, Oid retoid, Oid callingfunc) |
| To apply the "expand for radius search" pattern we need access to the expand function, so lookup the function Oid using the function name and type number. More... | |
| Oid | opFamilyAmOid (Oid opfamilyoid) |
| We only add index enhancements for indexes that support range-based searches like the && operator), so only implementations based on GIST and SPGIST. More... | |
| static int16 | temporal_get_strategy_by_type (meosType temptype, uint16_t index) |
| PGDLLEXPORT Datum | Temporal_supportfn (PG_FUNCTION_ARGS) |
| Support function for temporal types. More... | |
| Datum | temporal_supportfn_ext (FunctionCallInfo fcinfo, TemporalFamily tempfamily) |
| For functions that we want enhanced with spatial index lookups, add this support function to the SQL function definition, for example: More... | |
| PGDLLEXPORT Datum | Tnumber_supportfn (PG_FUNCTION_ARGS) |
| Support function for temporal number types. More... | |
| PGDLLEXPORT Datum | Tpoint_supportfn (PG_FUNCTION_ARGS) |
| Support function for temporal number types. More... | |
| static meosType | type_to_bbox (meosType type) |
| Transform the constant into a period. More... | |
