the decision not to make renamerel() update the sequence name that
is stored within sequences themselves (thanks to Tom Lane), and adds
some rudimentary regression tests for ALTER TABLE ... RENAME on
non-table relations.

when added by alter table add constraint. The first file
patches backend/commands/command.c and the latter is a patch
to the alter table regression test.

in referencing and referenced columns of an fk constraint
aren't comparable using '=' at constraint definition time
rather than insert/update time.

I believe this should fix the issue that Philip Warner
noticed about the check for unique constraints meeting the
referenced keys of a foreign key constraint allowing the
specification of a subset of a foreign key instead of
rejecting it. I also added tests for a base case of
this to the foreign key and alter table tests and patches
for expected output.
didn't hear anything about, but which would
have broken with the function manager changes
anyway.
Well, this patch checks that a unique constraint
of some form (unique or pk) is on the referenced
columns of an FK constraint and that the columns
in the referencing table exist at creation time.
The former is to move closer to SQL compatibility
and the latter is in answer to a bug report.
I also added a basic check of this functionality
to the alter table and foreign key regression
tests.

Implement TIME WITH TIME ZONE type (timetz internal type).
Remap length() for character strings to CHAR_LENGTH() for SQL92
and to remove the ambiguity with geometric length() functions.
Keep length() for character strings for backward compatibility.
Shrink stored views by removing internal column name list from visible rte.
Implement min(), max() for time and timetz data types.
Implement conversion of TIME to INTERVAL.
Implement abs(), mod(), fac() for the int8 data type.
Rename some math functions to generic names:
round(), sqrt(), cbrt(), pow(), etc.
Rename NUMERIC power() function to pow().
Fix int2 factorial to calculate result in int4.
Enhance the Oracle compatibility function translate() to work with string
arguments (from Edwin Ramirez).
Modify pg_proc system table to remove OID holes.
tests for the Foreign Key support in 7.0 which
was made against a CVS copy from this

accesses versus sequential accesses, a (very crude) estimate of the
effects of caching on random page accesses, and cost to evaluate WHERE-
clause expressions. Export critical parameters for this model as SET
variables. Also, create SET variables for the planner's enable flags
(enable_seqscan, enable_indexscan, etc) so that these can be controlled
more conveniently than via PGOPTIONS.
Planner now estimates both startup cost (cost before retrieving
first tuple) and total cost of each path, so it can optimize queries
with LIMIT on a reasonable basis by interpolating between these costs.
Same facility is a win for EXISTS(...) subqueries and some other cases.
Redesign pathkey representation to achieve a major speedup in planning
(I saw as much as 5X on a 10-way join); also minor changes in planner
to reduce memory consumption by recycling discarded Path nodes and
not constructing unnecessary lists.
Minor cleanups to display more-plausible costs in some cases in
EXPLAIN output.
Initdb forced by change in interface to index cost estimation
functions.
1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql. 4. Modify
the regression test scripts and outputs to match up.
Might require new regression.{SYSTEM} files...
