* SELECT pg_class FROM pg_class generates strange error
* Alter TABLE ADD COLUMN does not honor DEFAULT, add CONSTRAINT
* -Creating index of TIMESTAMP & RELTIME fails, or rename to DATETIME(Thomas)
-* SELECT foo UNION SELECT foo is incorrectly simplified to SELECT foo
+* -SELECT foo UNION SELECT foo is incorrectly simplified to SELECT foo
* Unique index on base column not honored on inserts from inherited table
INSERT INTO inherit_table (unique_index_col) VALUES (dup) should fail
[inherit]
-* Be smarter about promoting types when UNION merges different data types
-* redesign INSERT ... SELECT to have two levels of target list
+* -Be smarter about promoting types when UNION merges different data types

VIEWS
-* Views containing aggregates sometimes fail(Jan)
+* -Views containing aggregates sometimes fail(Jan)
* Creating view and inheriting the view causes view* to show
duplicates(inherit)
* -Disallow LOCK on view(Mark Hollomon)
* Buffer reference counting bugfixes
* Fix libpq bug that causes it to drop backend error message sent
just before connection closure (ie, any FATAL error message)

-* SELECT ... UNION ... GROUP BY fails if column types disagree, no type
+* -SELECT ... UNION ... ORDER BY fails when sort expr not in result list
+* -SELECT ... UNION ... GROUP BY fails if column types disagree, no type
promotion occurs
* Modification of pg_class can happen while table in use by
another backend. Might lead to MVCC inside of syscache
URGENT
* -Add OUTER joins, left and right[outer](Tom, Thomas)
-* Allow long tuples by chaining or auto-storing outside db (TOAST)(Jan)

- o Not to stuff everything as files in a single directory, hash dirs
- o Allow large object vacuuming
- o Tables that start with xinv confused to be large objects

+* -Support UNION/INTERSECT/EXCEPT in sub-selects
* -Allow DELETE and UPDATE to use inheritance
* Allow INSERT INTO my_table VALUES (a, b, c, DEFAULT, x, y, z, ...)
* Allow BINARY option to SELECT, like we do with DECLARE
with after-row images(Vadim) [logging](Vadim)(in-progress)
* Populate backend status area and write program to dump status data
* Make oid use unsigned int more reliably, pg_atoi()
-* Put sort files, large objects in their own directory
+* Put sort files 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](Tom)

[subquery]
-* use fmgr_info()/fmgr_faddr() instead of fmgr() calls in high-traffic
+* -use fmgr_info()/fmgr_faddr() instead of fmgr() calls in high-traffic
places, like GROUP BY, UNIQUE, index processing, etc.
