by Ken Ashcraft's report. I think there is no actual bug here since if
the int32 value does wrap a little bit, palloc will still reject it.
Still it's better that the code be obviously correct.

find_my_exec/find_other_exec(). Remove passing of progname to these
functions as they can find that out from argv[0], which they already
have.
Make get_progname return const char *, and update all progname variables
to be const char *.

all the code that looks for other binaries. I move FindExec into
port/exec.c (and renamed it to find_my_binary()). I also added
find_other_binary that looks for another binary in the same directory as
the calling program, and checks the version string.
The only behavior change was that initdb and pg_dump would look in the
hard-coded bindir directory if it can't find the requested binary in the
same directory as the caller. The new code throws an error. The old
behavior seemed too error prone for version mismatches.

infinite-loop problems if a bogus data length is passed.

permissions tests in about the same amount of code as before. Exactly what
the GRANT/REVOKE code ought to be doing is still up for debate, but this
should be helpful in any case, and it already solves an efficiency problem
in executor startup.

Didier Moens. Bug is new in 7.4, and was caused by not updating everyplace
I should've when replacing locParam markers by allParam.
Add a regression test to catch related errors in future.

rather than allowing them only in a few special cases as before. In
particular you can now pass a ROW() construct to a function that accepts
a rowtype parameter. Internal generation of RowExprs fixes a number of
corner cases that used to not work very well, such as referencing the
whole-row result of a JOIN or subquery. This represents a further step in
the work I started a month or so back to make rowtype values into
first-class citizens.

- Added "extern C" flags for C++ compiler. Hopefully I got that one right.

ALTER SET STATISTICS for functional indexes.

This simplifies and speeds up the reader by letting it get the representation
right the first time, rather than correcting it after-the-fact. Also,
after int and OID lists become separate node types per Neil's pending
patch, this will let us treat these lists as just plain Nodes instead
of requiring separate read/write macros the way we have now.

costing us lots more to maintain than it was worth. On shared tables
it was of exactly zero benefit because we couldn't trust it to be
up to date. On temp tables it sometimes saved an lseek, but not often
enough to be worth getting excited about. And the real problem was that
we forced an lseek on every relcache flush in order to update the field.
So all in all it seems best to lose the complexity.

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.

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

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.

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.
