ef590e101e Changed ExecConstraints() and ExecRelCheck() to cache the constraints 
qualification expression trees in the execution state. Prevents from
memory exhaustion on INSERT, UPDATE or COPY to tables that have CHECK
constraints. Speedup against the variant using freeObject() is more than
factor 2.

a7ad43cd18 Included patches make some enhancements to the multi-byte support. 
o allow to use Big5 (a Chinese encoding used in Taiwan) as a client
  encoding. In this case the server side encoding should be EUC_TW

o add EUC_TW and Big5 test cases to the regression and the mb test
  (contributed by Jonah Kuo)

o fix mistake in include/mb/pg_wchar.h. An encoding id for EUC_TW was
  not correct (was 3 and now is 4)

o update documents (doc/README.mb and README.mb.jp)

o update psql helpfile (bin/psql/psqlHelp.h)

422221c90d Another SELECT speedup: extract OIDs of column print functions 
only once per SELECT, not once per tuple.  10% here, 10% there,
pretty soon you're talking about real speedups ...

d03e98737c Replace typtoout() and gettypelem() with a single routine, 
so that fetching an attribute value needs only one SearchSysCacheTuple call
instead of two redundant searches.  This speeds up a large SELECT by about
ten percent, and probably will help GROUP BY and SELECT DISTINCT too.

c91dbcc5c7 The following patch finishes primary key support. Previously, when 
a field was labelled as a primary key, the system automatically
created a unique index on the field.  This patch extends it so
that the index has the indisprimary field set.  You can pull a list
of primary keys with the followiing select.

SELECT pg_class.relname, pg_attribute.attname
    FROM pg_class, pg_attribute, pg_index
    WHERE pg_class.oid = pg_attribute.attrelid AND
        pg_class.oid = pg_index.indrelid AND
        pg_index.indkey[0] = pg_attribute.attnum AND
        pg_index.indisunique = 't';

There is nothing in this patch that modifies the template database to
set the indisprimary attribute for system tables.  Should they be
changed or should we only be concerned with user tables?
