Обсуждение: relkind check in info.c
Hi, I see that PGAPI_Tables() has a relkind check that only seems to include tables and views. Does it make sense to have it consider materialized views as well? I don't know anything about psqlodbc -- I'm just going by a question in the spanish list: http://www.postgresql.org/message-id/53287159.7040009@gmail.com -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services

I am noting as well that we should list it when invocating SQL_ALL_TABLE_TYPES. A patch to do that is simple, and not worth an additional regression test IMO, just to avoid the pain to have version-related regression tests... Regards, -- Michael

Just adding that a similar thing should be done with foreign tables. -- Michael

We need to decide to what to return in the table_type column for them. "FOREIGN TABLE" and "MATERIALIZED VIEW" would be natural choices. But it would be good to return the same string that other DBMS's return for those things. What does SQL Server's driver return for materialized views? I'm not aware of any other DBMS that implements foreign tables per the spec, but e.g DB2 has "remote tables" and Oracle has "database links", which are similar features. I wonder what table type do they return. - Heikki

I wonder what table type do they return. Poking a little bit that, I finished with the patch attached, with some regression tests attached. It may not be the most beautiful patch ever, but it is consistent with the current way code is made and it has the merit to be simple. Regards, -- Michael
