Some items completed and removed.

---------------------------------------------------------------------------


Default of '' causes crash in some cases
shift/reduce conflict in grammar, SELECT ... FOR [UPDATE|CURSOR]
create table "AA" ( x int4 , y serial ); insert into "AA" (x) values (1); fails
SELECT 1; SELECT 2 fails when sent not via psql, semicolon problem
SELECT * FROM test WHERE test IN (SELECT * FROM test) fails with strange error
CREATE OPERATOR *= (leftarg=_varchar, rightarg=varchar, procedure=array_varchareq); fails, varchar is reserved word,
quoteswork
 
CLUSTER failure if vacuum has not been performed in a while
Improve Subplan list handling
Allow Subplans to use efficient joins(hash, merge) with upper variable
Improve NULL parameter passing into functions
Table with an element of type inet, will show "0.0.0.0/0" as "00/0"
When creating a table with either type inet or type cidr as a primary,unique  key, the "198.68.123.0/24" and
"198.68.123.0/27"are considered equal
 
Allow ESCAPE '\' at the end of LIKE for ANSI compliance, or rewrite theLIKE handling by rewriting the user string with
thesupplied ESCAPE
 
Fix leak for expressions?, aggregates?
Improve LIMIT processing by using index to limit rows processed
Allow "col AS name" to use name in WHERE clause?  Is this ANSI? Works in GROUP BY
Update reltuples from COPY command
nodeResults.c and parse_clause.c give compiler warnings
Move LIKE index optimization handling to the optimizer?
MVCC locking, deadlock, priorities?
Make sure pg_internal.init generation can't cause unreliability
SELECT ... WHERE col ~ '(foo|bar)' works, but CHECK on table always fails
CREATE INDEX zman_index ON test (date_trunc( 'day', zman ) datetime_ops) failsindex can't store constant parameters,
allowSQL function indexes?
 
Have hashjoins use portals, not fixed-size memory
DROP TABLE leaves INDEX file descriptor open
ALTER TABLE ADD COLUMN to inherited table put column in wrong place
resno's, sublevelsup corrupt when reaching rewrite system
crypt_loadpwdfile() is mixing and (mis)matching memory allocation protocols, trying to use pfree() to release pwd_cache
vectorfrom realloc()
 
3 = sum(x) in rewrite system is a problem

Do we want pg_dump -z to be the default?
pg_dump of groups fails
pg_dump -o -D does not work, and can not work currently, generate error?
pg_dump does not preserver NUMERIC precision, psql \d should show precision
dumping out sequences should not be counted in pg_dump display

CREATE VIEW ignores DISTINCT?
ORDER BY mixed with DISTINCT causes duplicates
CREATE TABLE t1 (a int4, b int4); CREATE VIEW v1 AS SELECT b, count(b)FROM t1 GROUP BY b; SELECT count FROM v1; fails

Markup sql.sgml, Stefan's intro to SQL
Markup cvs.sgml, cvs and cvsup howto
Add figures to sql.sgml and arch-dev.sgml, both from Stefan
Include Jose's date/time history in User's Guide (neat!)
Generate Admin, User, Programmer hardcopy postscript

DROP TABLE/RENAME TABLE doesn't remove extended files, *.1, *.2
Multi-segment indexes?
Vacuum of tables >2 gigs - NOTICE:  Can't truncate multi-segments relation

Make Serial its own type?
Add support for & operator
store binary-compatible type information in the system somewhere 
add ability to add comments to system tables using table/colname combination
process const=const parts of OR clause in separate pass
make oid use oidin/oidout not int4in/int4out in pg_type.h, make oid useunsigned int more reliably, pg_atoi()

I see the "AA" problem, and was just working in that code. Will look
at it.

> SELECT 1; SELECT 2 fails when sent not via psql, semicolon problem

I'm almost certain that this is from changes introduced by Stefan's
EXCEPT patches. There are some rules in gram.y which handle multiple
statements, and he commented them out to get rid of shift/reduce
conflicts he introduced :(

    Will  not  be  fixed in v6.5. I'll add an elog(ERROR, ...) to
    reject those view definitions during CREATE VIEW.

> CREATE TABLE t1 (a int4, b int4); CREATE VIEW v1 AS SELECT b, count(b)

    Fixed.

    SELECT b FROM v1; still fails with

    ERROR:  union_planner: query is marked hasAggs, but I don't see any

    Must adjust hasAggs as final step in rewriter.
