anonymous return type SRF code. It gets rid of the superflous
'pg_locks_result' that Bruce/Tom had commented on. Otherwise, no
changes in functionality.

the 'override CPPFLAGS' to include the source directory during compile,
and makes the install target look in the proper place for the man page.
Changes are only required when building outside the source directory.

copying into a fixed-size buffer (in this case, a buffer of
NAMEDATALEN bytes). AFAICT nothing to worry about here, but worth
fixing anyway...

bit on the indexes.
I also attach clusterdb and clusterdb.sgml; both of them are blatant
rips of vacuumdb and vacuumdb.sgml, but get the job done. Please review
them, as I'm probably making a lot of mistakes with SGML and I can't
compile it here.
vacuumdb itself is not very comfortable to use when the databases have
passwords, because it has to connect once for each table (I can probably
make it connect only once for each database; should I?). Because of
this I added a mention of PGPASSWORDFILE in the documentation, but I
don't know if that is the correct place for that.

that ANALYZE would not gather any stats for a CHAR(255) column. I still
think a width threshold is appropriate for the reasons mentioned in the
code, but we can loosen it at least.

array header, and to compute sizing and alignment of array elements
the same way normal tuple access operations do --- viz, using the
tupmacs.h macros att_addlength and att_align. This makes the world
safe for arrays of cstrings or intervals, and should make it much
easier to write array-type-polymorphic functions; as examples see
the cleanups of array_out and contrib/array_iterator. By Joe Conway
and Tom Lane.

width types and varlena types, since with the introduction of CSTRING as
a more-or-less-real type, these concepts aren't identical. I've tried to
use varlena consistently to denote datatypes with typlen = -1, ie, they
have a length word and are potentially TOASTable; while the term variable
width covers both varlena and cstring (and, perhaps, someday other types
with other rules for computing the actual width). No code changes in this
commit except for renaming a couple macros.
|
|
value '-2' is used to indicate a variable-width type whose width is
computed as strlen(datum)+1. Everything that looks at typlen is updated
except for array support, which Joe Conway is working on; at the moment
it wouldn't work to try to create an array of cstring.

the server. Previously we allocated a new String object for the entire final
query we were sending to the database. If you had a big query, or especially
if you had large bind values you ended up with essentially two copies in memory.
This change will reuse the existing objects and therefore should take 1/2 the
memory it does today for a given query. This restructuring will also allow
in the future the ability to stream bytea data to the server instead of the current approach of pulling it all into memory.
I also fixed a test that was failing on a 7.2 database.
Also renamed some internal variables and some minor cleanup.

improve error message, cause a relation's TOAST table to be truncated
along with the relation.

for repeat(). Again, somewhat off-the-cuff, so I might have missed
something...
test=# select lpad('xxxxx',1431655765,'yyyyyyyyyyyyyyyy');
ERROR: Requested length too large
test=# select rpad('xxxxx',1431655765,'yyyyyyyyyyyyyyyy');
ERROR: Requested length too large
(That's on a Unicode DB, haven't tested other encodings but AFAICT
this fix should still work.)

Good point -- that wouldn't cause incorrect results or a security
problem, but it would reject input that we should really accept.
Revised patch is attached.

constraints
The issue with finding and removing foreign key constraints is no longer
an issue, so please apply the attached.
It does NOT check for rules or on delete triggers (old style foreign
keys) as those are difficult to deal with (remove, truncate, re-add).

bytealike to TEXT.
This leaves like_escape_bytea() without anything to do, but I left it in
place in anticipation of the eventual bytea pattern selectivity
functions. If there is agreement that this would be the best long term
solution, I'll take it as a TODO for 7.4.

replace(string, from, to)
-- replaces all occurrences of "from" in "string" to "to"
split(string, fldsep, column)
-- splits "string" on "fldsep" and returns "column" number piece
to_hex(int32_num) & to_hex(int64_num)
-- takes integer number and returns as hex string

from the core repository ... I haven't *moved* the libpq++ files out of the
tree, mainly as we want to keep them in place for past branches ...
Peter, I think I've covered all the files I need, and re-ran autoconf to make
sure the configure file is in place properly ...

with OPAQUE, as per recent pghackers discussion. I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

Use off_t and size_t in pg_dump to handle file offset arithmetic correctly.
|

code is broken, but any small change in the output format might overrun
the buffer with the old size.

From Rod Taylor.

FOUND is set whenever a SELECT INTO returns > 0 rows, *or* when an
INSERT, UPDATE, or DELETE affects > 0 rows. We implemented the first
part of this behavior, but not the second.
I also improved the documentation on the various situations in which
FOUND can be set (excluding inside FOR loops, which I still need to
think about), and added some regression tests for this behavior.
