* [PATCH] Handle element label and element label property objects in object address functions
@ 2026-04-23 09:27 Bertrand Drouvot <[email protected]>
0 siblings, 0 replies; 588+ messages in thread
From: Bertrand Drouvot @ 2026-04-23 09:27 UTC (permalink / raw)
getObjectTypeDescription() and getObjectIdentityParts() do not handle objects in
pg_propgraph_element_label and pg_propgraph_label_property catalogs. These
functions when called for handling a DDL that affects these objects causes
"unsupported object class" error. An error is reported when these functions are
called when pg_identify_object() and pg_identify_object_as_address() are invoked
with objects from the said catalogs.
The objects in these catalogs do not have a (user given) name but they can be
manipulated invdividually through ALTER PROPERTY GRAPH sub-commands. Hence they
need to be accessible to the event triggers. Handle these catalogs in the
respective functions.
