tempt a /tmp directory cleaner to remove it. Still another reason we
should never have put the sockets in /tmp in the first place ...

truncating to integer. Remove regress test that checks whether
4567890123456789 can be converted to float without loss; since that's
52 bits, it's on the hairy edge of failing with IEEE float8s, and indeed
rint seems to give platform-dependent results for it.

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.

New code is protected by FixBTree bool flag setted to FALSE, so
nothing should be affected by this untested approach.

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!

Dave Page

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

objects that Thomas pointed out might be a problem.
PPS. I have included and updated the comments from the original patch
request to reflect the changes made in this revised patch.
> Attached is a set of patches for a couple of bugs dealing with
> timestamps in JDBC.
>
> Bug#1) Incorrect timestamp stored in DB if client timezone different
> than DB.
> The buggy implementation of setTimestamp() in PreparedStatement simply
> used the toString() method of the java.sql.Timestamp object to convert
> to a string to send to the database. The format of this is yyyy-MM-dd
> hh:mm:ss.SSS which doesn't include any timezone information. Therefore
> the DB assumes its timezone since none is specified. That is OK if the
> timezone of the client and server are the same, however if they are
> different the wrong timestamp is received by the server. For example if
> the client is running in timezone GMT and wants to send the timestamp

> 12:00:00-08 which is 2000-01-12 04:00:00 in GMT. The fix is to send a

> There was another problem/fix mentioned on the email lists today by
> mcannon@internet.com which is also fixed by this patch:
>
> Bug#3) Fractional seconds lost when getting timestamp from the DB
> A patch by Jan Thomea handled the case of yyyy-MM-dd hh:mm:sszzzzzzzzz
> but not the fractional seconds version yyyy-MM-dd hh:mm:ss.SSzzzzzzzzz.
> The code is fixed to handle this case as well.

privkey.pem cert.pem.pw" if you just use "privkey.pem" in the following
openssl command (e.g. openssl rsa -in privkey.pem -out cert.pem".
But there is nothing wrong with it as it is now, as far as I can see.
