create_index_on_column() passed "graphid_ops" as an unqualified operator
class name, so it was resolved against the caller's search_path. Whenever
ag_catalog was not on the search_path, creating a label failed with
ERROR: operator class "graphid_ops" does not exist for access method "btree"
even for a fully qualified call such as
SELECT ag_catalog.create_graph('g');
The error is misleading: the operator class does exist, it is simply not
visible. This affected create_graph(), create_vlabel(), create_elabel(),
the CSV loader, and label creation from a CREATE or MERGE clause at query
time, since all of them reach create_label().
The unqualified name arrived with the id column indexes in apache#2117, so this
is a regression. Before that commit create_label() built no index and
resolved no name through the search_path. Every other object referenced by
the DDL that create_label() generates is already reached either by OID or
by an ag_catalog qualified name, so qualifying this one restores the
previous behaviour.

@NotHimmel Can you add a test case please |
Cover create_label() with ag_catalog off the search_path. The block calls create_graph(), create_vlabel(), create_elabel() and a cypher CREATE clause, all through ag_catalog qualified names, so it exercises both create_index_on_column() branches (the unique index on a vertex label's id column and the non-unique indexes on an edge label's start_id and end_id columns) plus label creation at query time. Without the qualified operator class name the first statement fails with ERROR: operator class "graphid_ops" does not exist for access method "btree"
