return true for exactly the characters treated as whitespace by their flex
scanners. Per report from Victor Snezhko and subsequent investigation.
Also fix a passel of unsafe usages of <ctype.h> functions, that is, ye olde
char-vs-unsigned-char issue. I won't miss <ctype.h> when we are finally
able to stop using it.
by abandoning the idea that it should say SERIAL in the dump. Instead,
dump serial sequences and column defaults just like regular ones.
Add a new backend command ALTER SEQUENCE OWNED BY to let pg_dump recreate
the sequence-to-column dependency that was formerly created "behind the
scenes" by SERIAL. This restores SERIAL to being truly "just a macro"
consisting of component operations that can be stated explicitly in SQL.
Furthermore, the new command allows sequence ownership to be reassigned,
so that old mistakes can be cleaned up.
Also, downgrade the OWNED-BY dependency from INTERNAL to AUTO, since there
is no longer any very compelling argument why the sequence couldn't be
dropped while keeping the column. (This forces initdb, to be sure the
right kinds of dependencies are in there.)
Along the way, add checks to prevent ALTER OWNER or SET SCHEMA on an
owned sequence; you can now only do this indirectly by changing the
owning table's owner or schema. This is an oversight in previous
releases, but probably not worth back-patching.
the opportunity to treat COUNT(*) as a zero-argument aggregate instead
of the old hack that equated it to COUNT(1); this is materially cleaner
(no more weird ANYOID cases) and ought to be at least a tiny bit faster.
Original patch by Sergey Koposov; review, documentation, simple regression
tests, pg_dump and psql support by moi.
I take out patch for this as a promise. This is client-build support of
MS-VC6+.
Fix for different getaddrinfo structure ordering on Win32 for IPv6.

was invoking obj_description() for each large object chunk, instead of once
per large object. This code is new as of 8.1, which may explain why the
problem hadn't been noticed already.
o remove many WIN32_CLIENT_ONLY defines
o add WIN32_ONLY_COMPILER define
o add 3rd argument to open() for portability
o add include/port/win32_msvc directory for

and there's only one place that's a kluge, ie, appendStringLiteralConn.
Note that pg_dump itself doesn't use appendStringLiteralConn, so its
behavior is not affected; only the other utility programs care.
o turns off escape_string_warning in pg_dumpall.c
o optionally use E'' for \password (undocumented option?)
o honor standard_conforming-strings for \copy (but not
support literal E'' strings)
o optionally use E'' for \d commands
o turn off escape_string_warning for createdb, createuser,

and standard_conforming_strings; likewise for the other client programs
that need it. As per previous discussion, a pg_dump dump now conforms
to the standard_conforming_strings setting of the source database.
We don't use E'' syntax in the dump, thereby improving portability of
the SQL. I added a SET escape_strings_warning = off command to keep
the dumps from getting a lot of back-chatter from that.
Per Coverity bug #304. Thanks to Martijn van Oosterhout for reporting it.
Zero out the pointer fields of PGresult so that these mistakes are more
easily catched, per discussion.
'off'. This allows pg_dump output with standard_conforming_strings =
'on' to generate proper strings that can be loaded into other databases
without the backslash doubling we typically do. I have added the
dumping of the standard_conforming_strings value to pg_dump.
I also added standard backslash handling for plpgsql.
identically named user and group: we merge these into a single entity
with LOGIN permission. Also, add ORDER BY commands to ensure consistent
dump ordering, for ease of comparing outputs from different installations.
make use of the recently added ability to create a shell type explicitly.
I also put in place some infrastructure to allow dump/no dump decisions
to be made separately for each database object, rather than the former
hardwired 'dump if in a dumpable schema' policy. This was needed anyway
for shell types so now seemed a convenient time to do it. The flexibility
isn't exposed to the user yet, but is ready for future extensions.
by decompiling the typdefaultbin expression, not just printing the typdefault
text which may be out-of-date or assume the wrong schema search path. (It's
the same hazard as for adbin vs adsrc in column defaults.) The catalogs.sgml
spec for pg_type implies that the correct procedure is to look to
typdefaultbin first and consider typdefault only if typdefaultbin is NULL.
I made dumping of both domains and base types do that, even though in the
current backend code typdefaultbin is always correct for domains and
typdefault for base types --- might as well try to future-proof it a little.
Per bug report from Alexander Galler.
comments on cluster global objects like databases, tablespaces, and
roles.
It touches a lot of places, but not much in the way of big changes. The
only design decision I made was to duplicate the query and manipulation
functions rather than to try and have them handle both shared and local
comments. I believe this is simpler for the code and not an issue for
callers because they know what type of object they are dealing with.
This has resulted in a shobj_description function analagous to
obj_description and backend functions [Create/Delete]SharedComments
mirroring the existing [Create/Delete]Comments functions.
pg_shdescription.h goes into src/include/catalog/

not print the owner name in the object comment.
eg:
--
-- Name: actor; Type: TABLE; Schema: public; Owner: chriskl; Tablespace:
--
Becomes:
--
-- Name: actor; Type: TABLE; Schema: public; Owner: -; Tablespace:
--
This makes it far easier to do 'user independent' dumps. Especially for
distribution to third parties.

Continue to support GRANT ON [TABLE] for sequences for backward
compatibility; issue warning for invalid sequence permissions.
[Backward compatibility warning message.]
Add USAGE permission for sequences that allows only currval() and
nextval(), not setval().
Mention object name in grant/revoke warnings because of possible
