* Disallow inherited columns with the same name as new columns
-* INSERT INTO ... SELECT with AS columns matching result columns problem
+* -INSERT INTO ... SELECT with AS columns matching result columns problem
* SELECT pg_class FROM pg_class generates strange error
* Alter TABLE ADD COLUMN does not honor DEFAULT, add CONSTRAINT
* Do not allow bpchar column creation without length
* SELECT foo UNION SELECT foo is incorrectly simplified to SELECT foo
* -INSERT ... SELECT ... GROUP BY groups by target columns not source columns(Tom)
* -CREATE TABLE test (a char(5) DEFAULT text '', b int4) fails on INSERT(Tom)
-* UNION with LIMIT fails
+* -UNION with LIMIT fails
* Unique index on base column not honored on inserts from inherited table
INSERT INTO inherit_table (unique_index_col) VALUES (dup) should fail
[inherit]
-* CREATE TABLE x AS SELECT 1 UNION SELECT 2 fails
-* CREATE TABLE test(col char(2) DEFAULT user) fails in length restriction
-* mismatched types in CREATE TABLE ... DEFAULT causes problems [default]

+* -CREATE TABLE test(col char(2) DEFAULT user) fails in length restriction
+* -mismatched types in CREATE TABLE ... DEFAULT causes problems [default]
* SELECT ... UNION ... ORDER BY fails when sort expr not in result list
* Be smarter about promoting types when UNION merges different data types
* SELECT ... UNION ... GROUP BY fails if column types disagree
* -select * from pg_class where oid in (0,-1)
* have INTERSECT/EXCEPT prevent duplicates unless ALL is specified
* prevent primary key of nine columns [primary]
-* SELECT COUNT('asdf') FROM pg_class WHERE oid=12 crashes
+* -SELECT COUNT('asdf') FROM pg_class WHERE oid=12 crashes
* SELECT DISTINCT ON col1 col1 col2 FROM tab1 is broken [distinct]

-* Allow compression of large fields or a compressed field type
+* -Allow compression of large fields or a compressed field type
* Large objects
o Fix large object mapping scheme, own typeid or reltype(Peter)
o Allow large text type to use large objects(Peter)
with after-row images(Vadim) [logging](Vadim)
* Populate backend status area and write program to dump status data
* Make oid use unsigned int more reliably, pg_atoi()
-* Allow subqueries in target list
+* -Allow subqueries in target list
* Put sort files, large objects in their own directory
* Do autocommit so always in a transaction block(?)
* Show location of syntax error in query [yacc]
* Redesign the function call interface to handle NULLs better [function]
* Document/trigger/rule so changes to pg_shadow recreate pg_pwd [pg_shadow]
* Missing optimizer selectivities for date, r-tree, etc. [optimizer]
-* Overhaul mdmgr/smgr to fix double unlinking and double opens, cleanup
+* -Overhaul mdmgr/smgr to fix double unlinking and double opens, cleanup
* Overhaul bufmgr/lockmgr/transaction manager
* Add PL/Perl(Mark Hollomon)

* -Add needed includes and removed unneeded include files(Bruce)
-* Make configure --enable-debug add -g on compile line
+* -Make configure --enable-debug add -g on compile line
* Does Mariposa source contain any other bug fixes?
* Remove SET KSQO option if OR processing is improved(Tom)
* rename 'createuser' to 'pg_createuser', and add 'pg_' to other commands
