below is the patch to have views to override the permission
checks for the accessed tables. Now we can do the following:
CREATE VIEW db_user AS SELECT
usename,
usesysid,
usecreatedb,
usetrace,
usecatupd,
'**********'::text as passwd,
valuntil
FROM pg_user;
REVOKE ALL ON pg_user FROM public;
REVOKE ALL ON db_user FROM public;
GRANT SELECT ON db_user TO public;
varchar length.
Cleans up code so attlen is always length.
Removed varchar() hack added earlier.
Will fix bug in selecting varchar() fields, and varchar() can be
variable length.
Pass List* of Aggregs into executor, and create needed array there.
No longer need to double-processs Aggregs with second copy in Query.
Fix crash when doing:
select sum(x+1) from test where 1 > 0;
Changes:
* Unique index capability works using the syntax 'create unique
index'.
* Duplicate OID's in the system tables are removed. I put
little scripts called 'duplicate_oids' and 'find_oid' in
include/catalog that help to find and remove duplicate OID's.
I also moved 'unused_oids' from backend/catalog to
include/catalog, since it has to be in the same directory
as the include files in order to work.
* The backend tries converting the name of a function or aggregate
to all lowercase if the original name given doesn't work (mostly
for compatibility with ODBC).
* You can 'SELECT NULL' to your heart's content.
* I put my _bt_updateitem fix in instead, which uses
_bt_insertonpg so that even if the new key is so big that
the page has to be split, everything still works.
* All literal references to system catalog OID's have been
replaced with references to define'd constants from the catalog
header files.
* I added a couple of node copy functions. I think this was a
preliminary attempt to get rules to work.
Here's a couple more small fixes that I've made to make my runtime
checker happy with the code. More along the lines of those that
I sent in the past, ie, a pointer to an array != the name of
an array. The last patch is that I mailed about yesterday -- I got
two replies of "do it", so it's done. As far as I can tell, however,
the function in question is never called by pg95, so either way
it can't hurt...
