ODBC driver on Windows 9X/ME/NT/2K when using the later versions of the
driver that don't have the Installshield installation:
1) Install psqlodbc.dll in to C:\Windows\System or C:\Winnt\System32
2) Add the registry settings in the attached file using regedit.
A useful addition to src/interfaces/odbc perhaps?

bits in JDBC & the first set of tools into contrib.
This is the third, and deals with enabling JDBC to be compiled with the main
source.
What it does is add a new option to configure: --with-java
This option tells configure to look for ant (our build tool of choice) and
if found, it then compiles both the JDBC driver and the new tools as part
of the normal make.
Also, when the postgresql install is done, all the .jar files are also
installed into the ${PGLIB}/java directory (thought best to keep then separate)
Now I had some conflicts when this applied so could someone please double check
that everything is ok?

am talking with Thomas Lockhart about the idea of bringing the PyGreSQL
version number into alignment with PostgreSQL so this may change to 7.1
before the release.
I have added to the copyright to indicate that from now on the PostgreSQL
copyright will apply. If someone wants to make that clearer please do.
The existing copyrights need to stay there for now but if necessary I can
ask Pascal Andre if he agrees to a different wording.
Added reference to the Python DB-API 2.0 compliant API wrapper.
Added reference to the PyGreSQL mailing list.
in Turkish locale. Keywords are now checked under pure ASCII case-folding
rules ('A'-'Z'->'a'-'z' and nothing else). However, once a word is
determined not to be a keyword, it will be case-folded under the current
locale, same as before. See pghackers discussion 20-Feb-01.

- Reduced the object overhead in PreparedStatement by reusing the same
StringBuffer object throughout. Similarly SimpleDateStamp's are alse
reused in a thread save manner.
- Implemented in PreparedStatement: setNull(), setDate/Time/Timestamp
using Calendar, setBlob(), setCharacterStream()
- Clob's are now implemented in ResultSet & PreparedStatement!
- Implemented a lot of DatabaseMetaData & ResultSetMetaData methods.
We have about 18 unimplemented methods left in JDBC2 at the current
time.
automatically to compensate the lack of automatic
conversion functionality of PostgreSQL server.
For example if there's a numeric type binding
1.2567 --> 1.2567::numeric.
I hope this change would enable the use of numeric
type in MS-Access etc.
Thanks Hiroki Kataoka for his checking my code.
per recent discussion in pgsql-odbc. Now SELECT is
a boundary but VACUUM isn't.
2) Put back the error handling behavior. When elog(ERROR)
was detected the driver automatically issue "ABORT"
if a transaction is in progress.
3) Driver version is 7.01.0003(Dave already set it but
it was put back).
- Fixed bug in LargeObject & BlobOutputStream where the stream's output
was not flushed when either the stream or the blob were closed.
- Fixed PreparedStatement.setBinaryStream() where it ignored the length
Tue Feb 13 16:33:00 GMT 2001 peter@retep.org.uk
- More TestCases implemented. Refined the test suite api's.
- Removed need for SimpleDateFormat in ResultSet.getDate() improving
performance.
- Rewrote ResultSet.getTime() so that it uses JDK api's better.
Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk
- Added MiscTest to hold reported problems from users.
- Fixed PGMoney.
- JBuilder4/JDBCExplorer now works with Money fields. Patched Field &
ResultSet (lots of methods) for this one. Also changed cash/money to
return type DOUBLE not DECIMAL. This broke JBuilder as zero scale
BigDecimal's can't have decimal places!
- When a Statement is reused, the previous ResultSet is now closed.
- Removed deprecated call in ResultSet.getTime()
Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk
- Changed a couple of settings in DatabaseMetaData where 7.1 now
supports those features
- Implemented the DatabaseMetaData TestCase.
Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk
- Added comment to Connection.isClosed() explaining why we deviate from
the JDBC2 specification.
- Fixed bug where the Isolation Level is lost while in autocommit mode.
- Fixed bug where several calls to getTransactionIsolationLevel()
returned the first call's result.
1) Tidies up the Datasource Dialogue now the version options are gone.
2) Tidies a comment in info.c.
3) Increments all version numbers to 07.01.0003 to take account of recent
revisions.

are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
The driver version is 07.01.0002 now.
1) initialized pg_version by DSN's protocol info
so that we could always use pg_version info
once a connection is established (pg_version()
didn't exist before 6.4). PROTOCOL_XX() macros
are removed(except from connection.[ch]).
2) provided a few macros to encapsulate connection's
version info and replaced existent comparison
stuff by those macros.
3) change SQLTables() so that 7.1 servers could show
views.
In addtion, the following patch from Dave Page is applied.
This patch fixes a bug in SQLGetInfo for SQL_DBMS_VER which corrupted the
driver version string. The driver version number has also been incremented
to 07.01.0002.
Regards, Dave. <<odbc.diff>>
- Some minor additions to Statement to make our own extensions more
portable.
- Statement.close() will now call ResultSet.close() rather than just
dissasociating with it.
- Fixed bug where Statement.setMaxRows() was a global setting. Now
limited to just itself.
- Changed LargeObject.read(byte[],int,int) to return the actual number
of bytes read (used to be void).
- LargeObject now supports InputStream's!
- PreparedStatement.setBinaryStream() now works!
- ResultSet.getBinaryStream() now returns an InputStream that doesn't
copy the blob into memory first!
- Connection.isClosed() now tests to see if the connection is still alive
rather than if it thinks it's alive.
and two 'win32.mak'. Addresses the following:
1) Oops. Spelled fcntl.h wrong in the last one. D'uh.
2) PG_VERSION changed to be defined with " around it. psql/command.c failed
to compile without that.
3) Changed makefiles to use "/MD" and link both psql and libpq.dll against
MSVCRT.DLL instead of a static library. This takes care of the
crash-upon-free in psql.
I *think* this is what is on the "Open 7.1 Items" list as "Magnus Hagander
ODBC Issues?". It has nothing to do with ODBC, but it's the only issue I've
been involved with...

dialogue from '6.4/6.5' to '6.5+' and removes some C++ comments from
resource.h (which VC++ insists on putting there).
odbc2.diff adds code to query the PostgreSQL version upon connection. This
is then used to determine what values to return for from SQLGetInfo for
SQL_DBMS_VER, SQL_MAX_ROW_SIZE, SQL_MAX_STATEMENT_LEN, SQL_OJ_CAPABILITIES
and SQL_OUTER_JOINS. The version string as returned by SELECT vERSION() (as
a char array) and the major.minor version number (as a flost) have been
added to the ConnectionClass structure.

some more osteric bugs is easier. If only 1 arg is supplied and it's
of type Exception, then that Exception's stacktrace is now included.
This was done as there's been a report of an unusual bug during connection.
This will make this sort of bug hunting easier from now on.
problems with char array sizes having set a couple of constants to 0 for
unlimited query length and row length. This additional patch cleans those
problems up by defining a new constant (STD_STATEMENT_LEN) to 65536 and
using that in place of MAX_STATEMENT_LEN.
Another constant (MAX_MESSAGE_LEN) was defined as 2*BLCKSZ, but is now
65536. This is used to define the length of the message buffer in a number
of places and as I understand it (probably not that well!) therefore also
places a limit on the query length. Fixing this properly is beyond my
capabilities but 65536 should hopefully be large enough for most people.
Apologies for being over-enthusiastic and posting 3 patches in one day
rather than 1 better tested one!

In addition to my earlier patch, this one adds support for SQLGetInfo
SQL_OJ_CAPABILITIES to the ODBC driver.

following but it does *not* check whether the user is connected to
PostgreSQL 7.0.x or 7.1 first (as would be required for some of the
features) - the driver doesn't do this at all afaik and it's beyond my
capabilities to implement such checking in code that doesn't look like it
was written by my 1 year old daughter!
1) The driver now reports no maximum query length (SQL_MAX_QUERY_SIZE).
2) The driver now reports no maximum row length (SQL_MAX_ROW_SIZE).
3) The driver now reports that Outer Joins are supported (SQL_OUTER_JOINS),
but still does not report oj capabilities (SQL_OJ_CAPABILITIES).
4) The version number has been incremented to 7.1.0000 in psqlodbc.h *and*
psqlodbc.rc

PPS. I have included and updated the comments from the original patch

Query used for checking foreign key triggers
returns too many results when there're more than one foreign
key in a table. It happens because only table's oid is used to
link between pg_trigger with INSERT check and pg_trigger with
UPDATE/DELETE check.
I think there should be enough to add following conditions
into WHERE clause of that query:
AND pt.tgconstrname = pg_trigger.tgconstrname
AND pt.tgconstrname = pg_trigger_1.tgconstrname
