Structure to store the value of various constants.
This is needed to uniquely identify types, functions, etc., in PostgreSQL through their Object Identifier Types (OIDs).
Definition at line 115 of file provsql_utils.h.
| Oid constants_t::GATE_TYPE_TO_OID[nb_gate_types] |
Array of the OID of each provenance_gate ENUM value.
Definition at line 137 of file provsql_utils.h.
| Oid constants_t::OID_FUNCTION_AGG_TOKEN_UUID |
OID of the agg_token_uuid FUNCTION.
Definition at line 145 of file provsql_utils.h.
| Oid constants_t::OID_FUNCTION_ARRAY_AGG |
OID of the array_agg FUNCTION.
Definition at line 129 of file provsql_utils.h.
| Oid constants_t::OID_FUNCTION_ASSUME_BOOLEAN |
OID of provsql.assume_boolean(uuid)->uuid.
Installed by the 1.5.0--1.6.0 upgrade script. Wraps its child in a fresh gate_assumed_boolean and returns the wrapper's UUID. When InvalidOid the safe-query rewriter (and any other Boolean-only rewrite that needs the marker) is effectively disabled even if provsql.boolean_provenance is on: the rewriter refuses to produce unmarked roots on a schema that cannot enforce the semiring-compatibility check.
