IIRC we had rough consensus for switching the default setting to integer timestamps in 8.4. Perhaps it would be better for the Win32 build to wait till 8.4 before switching, for consistency with other platforms. The switch is in that it's the default on the MSVC build. So two different decisions (making that the default on MSVC, and making the MSVC build the default) together made that third. I'm fine dropping the default on MSVC until 8.4, if it's going to happen then. The downside then is that people won't be able to upgrade to the next beta without initdb, right? Which isn't too good, but it's better to make such a change during beta than to have to do it during release... //Magnus ---(end of broadcast)--- TIP 5: don't forget to increase your free space map settings

[BUGS] 8.3b2: problem using COPY ... TO/FROM .... BINARY
hi there i'm not sure it its really a bug - the manual specifies that COPY ... BINARY between different PGSQL versions might be problematic. nevertheless: i've imported several tables from 8.2.5 to 8.3b2 without any problems, until one table produced an error on a timestamp field: from pgsql 8.2.5: COPY users.ratings TO '/temp/ratings' BINARY; pgsql 8.3b2: COPY users.ratings FROM '/temp/ratings' BINARY; 2007-11-17 20:17:55 CET ERROR: timestamp out of range 2007-11-17 20:17:55 CET CONTEXT: COPY ratings, line 15081, column r_date when using COPY ... CVS/TEXT; everything works. by using CVS output, i was able do determine that the failing record is: 447,883,0.0,1999-01-01 00:00:00,f it seems to be the only timestamp that is failing, i've removed it from the source table and was able to binary copy the remaining data without problems. is this a bug or a feature? :) - thomas ps: is there a way to convert the binary file to plain sql to directly check which record fails? i've tried to use pg_restore to read the file, but it said does not appear to be a valid archive. ---(end of broadcast)--- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
