in favor of using the REINDEX TABLE apparatus, which does the same thing
simpler and faster. Also, make TRUNCATE not use cluster.c at all, but
just assign a new relfilenode and REINDEX. This partially addresses
Hartmut Raschick's complaint from last December that 7.4's TRUNCATE is
an order of magnitude slower than prior releases. By getting rid of
a lot of unnecessary catalog updates, these changes buy back about a
factor of two (on my system). The remaining overhead seems associated
with creating and deleting storage files, which we may not be able to
do much about without abandoning transaction safety for TRUNCATE.

printing the proper error message out of the common path.

safely be marked immutable, since their results don't depend on the
TimeZone GUC variable. Per recent discussion.

- Fixed bug that reversed string length in typedefs.
- Added portability file to pgtypeslib.

by the SQL spec and by our parser. Thanks to Jonathan Scott for finding
this longstanding error.

have a more proper GUC based test.
Also change error return code to ERRCODE_INVALID_PARAMETER_VALUE so it
matches the old error return code.

conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

recovering from an unexpected backend termination.
The remaining patches are to allow whitespace in db/install directory
names.

modify. Also fix a passel of problems with ALTER TABLE CLUSTER ON:
failure to check that the index is safe to cluster on (or even belongs
to the indicated rel, or even exists), and failure to broadcast a relcache
flush event when changing an index's state.

* ALTER ... ADD COLUMN with defaults and NOT NULL constraints works per SQL
spec. A default is implemented by rewriting the table with the new value
stored in each row.
* ALTER COLUMN TYPE. You can change a column's datatype to anything you
want, so long as you can specify how to convert the old value. Rewrites
the table. (Possible future improvement: optimize no-op conversions such
as varchar(N) to varchar(N+1).)
* Multiple ALTER actions in a single ALTER TABLE command. You can perform
any number of column additions, type changes, and constraint additions with
only one pass over the table contents.
Basic documentation provided in ALTER TABLE ref page, but some more docs
work is needed.
Original patch from Rod Taylor, additional work from Tom Lane.
