Fix CLUSTER
Fix all NULL features
allow psql to print nulls meaningfully
-Fix compile and security of Kerberos V code
+Fix compile and security of Kerberos/GSSAPI code (Daniel Kalchev?)
Dropping a table twice causes corruption, drop/create not rollback-able
-SUM aggregate on no rows or null value should return NULL, not zero(Thomas)
SELECT on two tables where zero or one table in WHERE and target
- clause returns no rows
-fix system to use oid index using constant without cast to oid
+ clause returns no rows
COUNT on VIEW always returns zero (maybe because there is no oid for views?)
CREATE VIEW requires super-user priviledge
SELECT a[1] FROM test fails, it needs test.a[1]
INSERT INTO ... SELECT DISTINCT ... generates error on DISTINCT
pg_database.datdba is oid, should be int4
+fix array diffs in regression test
+can lo_export()/lo_import() read/write anywhere, causing a security problem?
+SELECT ... INTO TABLE ... with varchar()/char() types have zero-length fields
+Fix UPDATE key_table SET keyval=max(reftab.NUM)+1 WHERE tblname='reftab'
ENHANCEMENTS
------------
add domains
add sql3 recursive unions
add the concept of dataspaces
- allow conversion type casts on select target fields
+ allow conversion type casts on SELECT target fields
Allow compression of large fields or a compressed field type
Fix the rules system(Jan?)
robust
expand to allow tcl, perl, java,
generalize the function manager switch to pass
function sources to interpreter engines.
- remove time-travel feature(Vadim)
- reduce system column overhead(Vadmin)
- remove pg_time table(Vadim)
- allow row re-use without vacuum, maybe?(Vadim)
- split apart row removal function from statistics function
- can't vacuum large objects

Remove restriction that ORDER BY field must be in SELECT list(?)
Allow queries about owner of datbases, tables like:
SELECT u.usesysid FROM postgres.pg_user u;
DROP AGGREGATE should take in basetype as an arg(Darren)
Add word index for text fields, maybe with trigrams, i.e.:
' (cat | dog) & ! fox ' meaning text has cat or dog, but not fox
-Add common-sense constant type promotions
+-Add common-sense constant type promotions(Bruce)
Allow readline-type or editor command editing of multi-line SQL commands
-Allow pg_dump to dump all databases at a site in one command
-Allow function result to be used in GROUP BY
+-Allow pg_dump to dump all databases at a site in one command(Bruce)
Populate backend status area and write program to dump status data
Add ALTER TABLE DROP COLUMN feature
Remove stale files upon startup(Vivek)
Improve optimizer plan choice(Darren)
Add STDDEV/VARIANCE() function for standard deviation computation/variance
Add upper/lower functions
--Add table/column/function discription table indexed by oid
+Add table/column/function discription table indexed by oid
-make all identifiers case-insensitive(Bruce)
add pg_type attribute to identify types that need length (bpchar, varchar)
add UNIQUE capability to non-btree indexes
-improve auto-type casting
+allow GROUP BY on columns that are functions
+add non-ascii collating strings with strcoll() and setlocale()
+new DATE routines (Thomas)
PERFORMANCE
-----------
objects, when greater than 8K.
Use indexes in ORDER BY
Profile engine in INSERT's and other operations
-Speed up hash creation by using btree's fast sort/insert routines
+-Speed up hash creation by using btree's fast sort/insert routines(done)
Cache most recent query plan(s?)
Allow compression of log and meta data
Allow LIKE/wildcard matches to use indexes if the wildcard character is not first
Add FILLFACTOR to index creation
-Allow indexes to be used with OR clauses
+Allow indexes to be used with OR clauses(Vadim)
-Add column optimization statistics to vacuum(Bruce)
-Change pg_attribute.attnvals name to attdispursion and change type float4
update pg_statistic table to remove operator column
Update usermanual source
remove time-travel in documentation(Bruce)
added features used in grammer but not in docs, like :: and CAST
-add DECLARE manual pages
+add DECLARE manual page
PORTABILITY
-----------
-Windows NT port
- Mariposa project at Berkeley has a person who's working on this
-Win95 port, use GNU port or remove it?
-Merge i386_solaris and sparc_solaris into solaris
-Switch from PORTNAME to individual feature defines (use configure/autoconf?)
Change c.h "Index" and "bool" so they do not conflict with c++
