I don't think reporting booleans is a very good idea. It's better to report that some other way, like use one of the strings to report a "phase" of processing that we're currently performing. > IMHO, float progress parameters (st_progress_param_float) can be taken > out.

If they are not used, they shouldn't be included in this patch, but we should be open to adding them later if it proves useful. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
