(Using the new PostgreSQL v9.3.0)
I did a schema-only dump of the 'pg_catalog' schema in the hopes to
study how the built-in OPERATOR CLASSes are defined.
Doing so output a few warnings:
$ [pg930] pg_dump -s -n pg_catalog template1 > /tmp/pg_catalog.sql
pg_dump: WARNING: typtype of data type "any" appears to be invalid
pg_dump: WARNING: typtype of data type "anyarray" appears to be invalid
pg_dump: WARNING: typtype of data type "anyelement" appears to be invalid
pg_dump: WARNING: typtype of data type "anyenum" appears to be invalid
pg_dump: WARNING: typtype of data type "anynonarray" appears to be invalid
pg_dump: WARNING: typtype of data type "anyrange" appears to be invalid
pg_dump: WARNING: typtype of data type "cstring" appears to be invalid
pg_dump: WARNING: typtype of data type "event_trigger" appears to be invalid
pg_dump: WARNING: typtype of data type "fdw_handler" appears to be invalid
pg_dump: WARNING: typtype of data type "internal" appears to be invalid
pg_dump: WARNING: typtype of data type "language_handler" appears to be
invalid
pg_dump: WARNING: typtype of data type "opaque" appears to be invalid
pg_dump: WARNING: typtype of data type "record" appears to be invalid
pg_dump: WARNING: typtype of data type "trigger" appears to be invalid
pg_dump: WARNING: typtype of data type "void" appears to be invalid
Additionally, the operator classes seem to be incomplete in pg_dump's
output:
CREATE OPERATOR CLASS box_ops
DEFAULT FOR TYPE box USING gist AS
;
...
CREATE OPERATOR CLASS text_ops
DEFAULT FOR TYPE text USING btree AS
;
I'd expect them to be fully spec'd with OPERATOR, FUNCTION, and STORAGE
arguments.
Am I expecting too much against 'pg_catalog' or is something bugged?
