Hi!
I think I've got a nice TODO item for psql client:
When a client connects to a database which has unknown (newer)
version it might be advisable to 'fallback' some commands to use
INFORMATION_SCHEMA instead of system catalogs.
For instance when connected to 8.4dev server using 8.3 client,
after issuing \d foo_table you get:
ERROR: column "reltriggers" does not exist
LINE1: SELECT relhasindex, relkind, relchecks, reltriggers, relhasr....
Of course the information_schema will probably be less efficient
and won't have PostgreSQL-specific items like 'Has OIDs', but
the user experience should be better.
My question is: does it look like a good TODO item? :)
Best regards, Dawid
