Ignoring the one in alter.c's AlterObjectNamespace_oid, which only handles a small subset of the enum values, that gives the following warnings: /pgsql/source/master/src/backend/catalog/dependency.c: In function 'doDeletion': /pgsql/source/master/src/backend/catalog/dependency.c:1106:2: warning: enumeration value 'OCLASS_ROLE' not handled in switch [-Wswitch] switch (getObjectClass(object)) ^ /pgsql/source/master/src/backend/catalog/dependency.c:1106:2: warning: enumeration value 'OCLASS_DATABASE' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/catalog/dependency.c:1106:2: warning: enumeration value 'OCLASS_TBLSPACE' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/catalog/dependency.c:1106:2: warning: enumeration value 'OCLASS_SUBSCRIPTION' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/commands/tablecmds.c: In function 'ATExecAlterColumnType': /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_AM' not handled in switch [-Wswitch] switch (getObjectClass(&foundObject)) ^ /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_STATISTIC_EXT' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_EVENT_TRIGGER' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_PUBLICATION' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_PUBLICATION_REL' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_SUBSCRIPTION' not handled in switch [-Wswitch] /pgsql/source/master/src/backend/commands/tablecmds.c:9112:3: warning: enumeration value 'OCLASS_TRANSFORM' not handled in switch [-Wswitch] -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
