Marc G. Fournier	e4949f9fe5	From: Dan McGuirk <mcguirk@indirect.com> Subject: [HACKERS] better access control error messages This patch replaces the 'no such class or insufficient privilege' with distinct error messages that tell you whether the table really doesn't exist or whether access was denied.	29 years ago
Vadim B. Mikheev	8e90978146	Fixing bug in INDEXSCAN_PATCH: ExecInitIndexScan now works with operands of Param type and (!!!) postquel_execute() now substitutes param values before calling postquel_start().	29 years ago
Marc G. Fournier	07a65b2255	Commit of a MAJOR patch from Dan McGuirk <djm@indirect.com> 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.	29 years ago

Marc G. Fournier	796f78998e	Fixes: The problem is that the function arguments are not considered as possible key candidates for index scan and so only a sequential scan is possible inside the body of a function. I have therefore made some patches to the optimizer so that indices are now used also by functions. I have also moved the plan debug message from pg_eval to pg_plan so that it is printed also for plans genereated for function execution. I had also to add an index rescan to the executor because it ignored the parameters set in the execution state, they were flagged as runtime variables in ExecInitIndexScan but then never used by the executor so that the scan were always done with any key=1. Very odd. This means that an index rescan is now done twice for each function execution which uses an index, the first time when the index scan is initialized and the second when the actual function arguments are finally available for the execution. I don't know what is the cost of an double index scan but I suppose it is anyway less than the cost of a full sequential scan, at leat for large tables. This is my patch, you must also add -DINDEXSCAN_PATCH in Makefile.global to enable the changes. Submitted by: Massimo Dal Zotto <dz@cs.unitn.it>	29 years ago
