I believe that the attached patch is the correct solution -- I apologize
for the gyrations. With the attached patch, Cygwin libpq++ builds
cleanly again. The root cause was that DLLIMPORT was defaulting to
__declspec(dllimport) since BUILDING_DLL was *not* defined when building
the libpq++ DLL.
Unfortunately, to test my patch requires changing the following makefile:
src/interfaces/libpq++/examples/Makefile
and the #includes in all of the *.cc to build against the source tree
instead of the following hardcoded installation directory structure:
/usr/local/pgsql
I was able to manually build
src/interfaces/libpq++/examples/testlibpq0.exe
against my Cygwin libpq++ without errors. However, I have not tried to
actually test testlibpq0.exe.
Is this sufficient? Or, do you want me to clean up libpq++/examples too?
(Or, is it silly to even ask? :,)) Let me know how you want to proceed and
I will submit a patch to pgsql-patches.

This patch allows to compile libpgtcl.dll on Windows
with tcl > 8.0. I've tested it on WinNT (VC6.0), SUSE Linux (7.0)
and Solaris 2.6 with tcl 8.3.3.

really played it totally safe in my last suggestion, the system table might
pick up the msg but not the netmsg.dll, so better try both.
I also added a hex printout of the "errno" appended to all messages, that's
nicer.
If anyone hate my coding style, or that i'm using goto constructs, just tell
me, and i'll rework it into a nested if () thing.

If there's anyone out there who's actually using datatype-defined
default values, this will be an incompatible change in behavior ...
but the old behavior was so broken that I doubt anyone was using it.
Standardize on %X/%X as the formatting for XLOG position display --- we
had a couple of different formats before, and none of 'em were as useful
as hex offsets IMHO.

it wasn't entirely appropriate.
On SCO OpenServer, the man pages won't be installed at all until someone

Client headers are no longer in a subdirectory, since they have been made

Internal libpq headers are in a private subdirectory.
Server headers are in a private subdirectory. pg_config has a new option
to point there.
Since we're assuming a C++ compiler knows what 'bool' is, seems we
should assume it knows 'true' and 'false' too. This prevents problems
on some systems, per report from Leandro Fanzone.
for some reason displays a zero oid differently. Possibly we should
revert that schema change, but it's easy to make pg_dump accept both
spellings so I'll do that for now.

Also, since building PL/Perl without a shared libperl actually works on
some platforms we can enable it there to get some development happening.
I've only checked off linux right now, but others should be added in the

org.postgresql.util.Serialize and org.postgresql.jdbc2.PreparedStatement
that fixes the ability to "serialize" a simple java class into a
postgres table.
The current cvs seems completely broken in this support, so the patch
puts it into working condition, granted that there are many limitations
with serializing java classes into Postgres.
The code to do serialize appears to have been in the driver since
Postgres 6.4, according to some comments in the source. My code is not
adding any totally new ability to the driver, rather just fixing what
is there so that it actually is usable. I do not think that it should
affect any existing functions of the driver that people regularly
depend on.
The code is activated if you use jdbc2.PreparedStatement and try to
setObject some java class type that is unrecognized, like not String or
not some other primitive type. This will cause a sequence of function
calls that results in an instance of Serialize being instantiated for
the class type passed. The Serialize constructor will query pg_class
to see if it can find an existing table that matches the name of the
java class. If found, it will continue and try to use the table to
store the object, otherwise an SQL exception is thrown and no harm is
done. Serialize.create() has to be used to setup the table for a java
class before anything can really happen with this code other than an
SQLException (unless by some freak chance a table exists that it thinks
it can use).
I saw a difference in Serialize.java between 7.1.3 and 7.2devel that I
didn't notice before, so I had to redo my changes from the 7.2devel
version (why I had to resend this patch now). I was missing the
fixString stuff, which is nice and is imporant to ensure the inserts
will not fail due to embedded single quote or unescaped backslashes. I
changed that fixString function in Serialize just a little since there
is no need to muddle with escaping newlines: only escaping single quote
and literal backslashes is needed. Postgres appears to insert newlines
within strings without trouble.
buffer manager with 'pg_clog', a specialized access method modeled
on pg_xlog. This simplifies startup (don't need to play games to
open pg_log; among other things, OverrideTransactionSystem goes away),
should improve performance a little, and opens the door to recycling
commit log space by removing no-longer-needed segments of the commit
log. Actual recycling is not there yet, but I felt I should commit
this part separately since it'd still be useful if we chose not to
do transaction ID wraparound.
This patch moves the logic that looks up TypeOid, PGTypeName, and
SQLTypeName from Field to Connection. It is moved to connection since
it needs to differ from the jdbc1 to jdbc2 versions and Connection
already has different subclasses for the two driver versions. It also
made sense to move the logic to Connection as some of the logic was
already there anyway.

so it may be a transit problem. Also removed the 'txt' suffix
in case that was confusing some transport layer trying to be
too inteligent for our own good.
This may have been because the Array.java class from the
previous patch didn't seem to have made it into the snapshot
build for some reason. This patch should at least fix that issue.

It works on win2k here too but not on win98/95 or winNT.
Anyway, attached is the patch which uses Magnus's my_sock_strerror
function (renamed to winsock_strerror). The only difference is that
I put the code to load and unload netmsg.dll in the libpqdll.c
(is this OK Magnus?).

pgsql-hackers. pg_opclass now has a row for each opclass supported by each
index AM, not a row for each opclass name. This allows pg_opclass to show
directly whether an AM supports an opclass, and furthermore makes it possible
to store additional information about an opclass that might be AM-dependent.
pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we
previously expected the user to remember to provide in CREATE INDEX commands.
Lossiness is no longer an index-level property, but is associated with the
use of a particular operator in a particular index opclass.
Along the way, IndexSupportInitialize now uses the syscaches to retrieve
pg_amop and pg_amproc entries. I find this reduces backend launch time by
about ten percent, at the cost of a couple more special cases in catcache.c's
IndexScanOK.

You're right. Attached is an updated patch that also includes a message
in error.properties. I've attempted a French message in
errors_fr.properties but beware that I haven't written French in quite a
few years. Don't know Italian, German, or Dutch so I can't do those.

SQLxxxx() to PGAPI_xxxx().
2) Handle an escaped date/time format as a parameter.
3) Improve the tuple allocation a little.
4) The preparation of ODBC 3.0 a little.
5) Updatable cursors(may be deprecated before long).
attempt at a patch to 7.1.2 to support Array.
[I think I've solved the mangled patch problem. Hotmail seems to
try to format the text file, so gzipping it should solve this
problem.]
In this patch I've incorporated Barry's feedback. Specifically:
1) OIDs are no longer hard-coded into Array.java. In order to
support this change I added a getOID(String) method to Field.java
which receives a PostgreSQL field type and returns a value from
java.sql.Types. I couldn't get away from using OIDs altogether
because the JDBC spec for Array specifies that some methods return
a ResultSet. This requires I construct Field objects,
which means I need OIDs. At least this approach doesn't hard
code these values. A Hashtable cache has been added to Field
so that an SQL lookup isn't necessary (following the model already
in Field.java).
2) Rewired the base formatting code in ResultSet.java to use 'to'
methods, which are then exposed as static methods in ResultSet.
These methods are used in Array to format the data without
duplications in the code.
3) Artifact call to first() in ResultSet.getArray() removed.
Greg Zoller
includes two changes in the JDBC driver:
1) When connected to a backend >= 7.2: use obj_description() and
col_description() instead of direct access to pg_description.
2) In DatabaseMetaData.getTables()/getColumns()/getProcedures():
when there is no comment on the object, return null in the
REMARKS column of the ResultSet, instead of the default string
"no remarks".
Change 2 first appeared as a side-effect of change 1, but it is
actually more compliant with the JDBC spec: "String object
containing an explanatory comment on the table/column/procedure,
which may be null". The default string "no remarks" was strictly
speaking incorrect, as it could not be distinguished from a real
user comment "no remarks". So I removed the default string
completely.
Change 2 might break existing code that doesn't follow the JDBC
spec and isn't prepared to handle a null in the REMARKS column
of getTables()/getColumns()/getProcedures.
Patch tested with jdbc2 against both a 7.1 and a CVS tip
backend. I did not have a jdbc1 environment to build and test
with, but since the touched code is identical in jdbc1 and jdbc2
I don't foresee any problems.

has an alias SERIAL4 and a sister SERIAL8. SERIAL8 is just the same
except the created column is type int8 not int4.
initdb forced. Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences. (Which is
not out of the question, but I don't wanna do it.)
Allow pg_shadow to be MD5 encrypted.
Add ENCRYPTED/UNENCRYPTED option to CREATE/ALTER user.
Add password_encryption postgresql.conf option.
Update wire protocol version to 2.1.
for speed reasons; its result type also changes to int8. avg() on these
datatypes now accumulates the running sum in int8 for speed; but we still
deliver the final result as numeric, so that fractional accuracy is
preserved.
count() now counts and returns in int8, not int4. I am a little nervous
about this possibly breaking users' code, but there didn't seem to be
a strong sentiment for avoiding the problem. If we get complaints during
beta, we can change count back to int4 and add a "count8" aggregate.
For that matter, users can do it for themselves with a simple CREATE
AGGREGATE command; the int4inc function is still present, so no C hacking
is needed.
Also added max() and min() aggregates for OID that do proper unsigned
comparison, instead of piggybacking on int4 aggregates.
initdb forced.
a tad sloppy about generating the targetlist for some nodes, by generating
a tlist entry that claimed to be a constant when the value wasn't actually
constant. This caused setrefs.c to do the wrong thing later on.
syntax for language names (instead of 'string').
createlang now handles the case where a second language uses the same call
handler as an already installed language (e.g., plperl/plperlu).
droplang now handles the reverse case, i.e., dropping a language where
the call handler is still used by another language. Moreover, droplang
can now be used to drop any user-defined language, not just the supplied
ones.
Don't hardcode the maximum accepted server version, use PG_VERSION instead.
Install a notice processor so notices are handled like error messages.
Word smithing.
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.
Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.
initdb forced.
* Merges identical code from org.postgresql.jdbc[1|2].Statement into

2. support for 'pass-by-value' arguments - to test this
we used special opclass for int4 with values in range [0-2^15]
More testing will be done after resolving problem with
index_formtuple and implementation of B-tree using GiST
3. small patch to contrib modules (seg,cube,rtree_gist,intarray) -
mark functions as 'isstrict' where needed.
