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.

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.
