client-side AUTOCOMMIT mode now: '\set AUTOCOMMIT off' supports
SQL-spec commit behavior. Get rid of LO_TRANSACTION hack --- the
LO operations just work now, using libpq's ability to track the
transaction status. Add a VERBOSE variable to control verboseness
of error message display, and add a %T prompt-string code to show
current transaction-block status. Superuser state display in the
prompt string correctly follows SET SESSION AUTHORIZATION commands.
Control-C works to get out of COPY IN state.
comparison functions), replacing the highly bogus bitwise array_eq. Create
a btree index opclass for ANYARRAY --- it is now possible to create indexes
on array columns.
Arrange to cache the results of catalog lookups across multiple array
operations, instead of repeating the lookups on every call.
Add string_to_array and array_to_string functions.
Remove singleton_array, array_accum, array_assign, and array_subscript
functions, since these were for proof-of-concept and not intended to become
supported functions.
Minor adjustments to behavior in some corner cases with empty or
zero-dimensional arrays.
Joe Conway (with some editorializing by Tom Lane).
HH:MM:SS.SSS... when there is a nonzero part-of-a-day field in an
interval value. The seconds part used to be suppressed if zero,
but there's no equivalent behavior for timestamp, and since we're
modeling this format on timestamp it's probably wrong. Per complaint
and patch from Larry Rosenman.
This is no longer necessary or appropriate since we don't use zero typeid
as a wildcard anymore, and it fixes a nasty performance problem with
functions with many parameters. Per recent example from Reuven Lerner.
The attached fixes select_common_type() to support the below case:
create table t1( c1 int);
create domain dom_c1 int;
create table t2(c1 dom_c1);
select * from t1 join t2 using( c1 );
I didn't see a need for maintaining the domain as the preferred type. A
simple getBaseType() call on all elements of the list seems to be
enough.

after the CHECK. Cluster depends on the index name, so I thought it
wise to ensure all names are available, rather than leaving off the
CONSTRAINT "$n" portion for internally named constraints.
CREATE TABLE jkey (col integer primary key);
CREATE TABLE j (col integer REFERENCES jkey);
ALTER TABLE j ADD CHECK(col > 5);
This is a problem in 7.3 series as well as -Tip.

- LIKE <subtable> [ INCLUDING DEFAULTS | EXCLUDING DEFAULTS ]
- Quick cleanup of analyze.c function prototypes.
- New non-reserved keywords (INCLUDING, EXCLUDING, DEFAULTS), SQL 200X
Opted not to extend for check constraints at this time.
As per the definition that it's user defined columns, OIDs are NOT
inherited.
