Let's add it to the next distribution. This was not ready at the time of the 1.02 release. --------------------------------------------------------------------------- ================================================= TODO list (FAQ) for Postgres95 ================================================== last updated: Mon Aug 5 21:00:12 EDT 1996 current maintainer: Bruce Momjian (maillist@candle.pha.pa.us) original author: Jolly Chen (jolly@cs.berkeley.edu) RELIABILITY ----------- Overhaul mdmgr/smgr to fix double unlinking and double opens, cleanup Memory leaks (hunt and destroy with tools like Purify) fix unitialized reads of memory fix array over-runs of memory writes Re-visit and fix vacuum can't vacuum large objects can't shrink tables, pg_time and pg_log Fix all NULL features DROP AGGREGATE should take in basetype as an arg Add other language types for built-in functions expand to allow tcl, perl, java, generalize the function manager switch to pass function sources to interpreter engines. Fix large object mapping scheme not to stuff everything as files in a single directory Fix CLUSTER Prevent improper index creation Starting quote in insert string errors Change default decimal constant representation from float4 to float8 ALTER TABLE bug - running postgress process needs to re-read table definition Allow libpq to distinguish between text value '' and null Allow non-postgres users with createdb privs to destroydb's PERFORMANCE ----------- Optimizing disjunctive queries Other optimizer bugs Is fsync use optimized? Multi-representational types, a la Illustra. For example, have a text type that is stored in-tuple when less than 8K and in large objects, when greater than 8K. ENHANCEMENTS ------------ Add full ANSI SQL capabilities ( a vendor has offered to help) add subselects column constraints (using rules), esp. primary keys add DEFAULT, UNIQUE, RESTRAINT, and CHECK capabilities report "Not implemented" if valid syntax is supplied add OUTER joins make VIEWs updateable where possible add UNIONS, INTERSECTS, SUBTRACTS add temporary tables add assertions add domains add sql3 recursive unions add the concept of dataspaces Implement HAVING clause Implement IN qualifier Add a way to preserve oid's when doing dump and load if not, make oid's accessable in insert rules Add word index for text fields, maybe with trigrams, i.e.: ' (cat | dog) & ! fox ' meaning text has cat or dog, but not fox Allow compression of large fields or a compressed field type Fix the rules system robust making INSTEAD rules work Full set of text operations and functions word searches, concat, upper/lower(), max() on text, char Replace table-level locking with row or page-level locking Large objects overwriting blocks has problems there are other problems, too. Better interface for adding to pg_group Make multi-field indexes easier to create allow optimizer to effectively use parameters without accessing table Improve debugging output Add int8 type Add table comments Add support for tables >2G Incorporate the PERL PG95 interface library into source tree Threaded version of the server or libpq Add REGEX internationalization DOCUMENTATION ------------- Better documentation. Write a real book on postgres, perhaps? Document OPENLINK fsync patch Update usermanual source Reduce size of regression diffs PORTABILITY ----------- Windows NT port Mariposa project at Berkeley has a person who's working on this Binary distributions for linux Merge bsdi_2_1 to bsdi Merge i386_solaris and sparc_solaris into solaris
