Hi hackers,
When a table column is referenced by a property graph, the property
name stored in pg_propgraph_property.pgpname would become stale after
a column rename. This caused GRAPH_TABLE queries to fail with the new
column name ("property does not exist") while the old (dead) name
continued to work. pg_get_propgraphdef() would also emit confusing
output like "new_col AS old_col".Fix by checking pg_depend in renameatt_internal() for PropgraphLabelPropertyRelationId entries that reference the column being renamed. If any exist, raise an error directing the user to drop the property graph first. Thanks, Satya
