Subject: pgsql: Add concept of invalid value to SysCacheIdentifier
Date: Wed, 18 Feb 2026 00:26:35 +0000
Message-ID: <[email protected]> (raw)
Add concept of invalid value to SysCacheIdentifier
This commit tweaks the generation of the syscache IDs for the enum
SysCacheIdentifier to now include an invalid value, with -1 assigned as
value. The concept of an invalid syscache ID exists when handling
lookups of a ObjectAddress, based on their set of properties in
ObjectPropertyType. -1 is used for the case where an object type has no
option for a syscache lookup.
This has been found as independently useful while discussing a switch of
SysCacheIdentifier to a typedef, as we already have places that want to
know about the concept of an invalid value when dealing with
ObjectAddresses.
