# duplicate_oids
|
|
# Identifies any manually-assigned OIDs that are used multiple times
|
|
# in the Postgres catalog data.
|
|
#
|
|
# While duplicate OIDs would only cause a failure if they appear in
|
|
# the same catalog, our project policy is that manually assigned OIDs
|
|
# should be globally unique, to avoid confusion.
