Author switching from 7.4.1 to 8.0-311 jdbc driver

Hi,

I am proposing a change to the newer 8.0 jdbc driver - it seems to clear
up some odd things I was seeing logged heavily:

2005-04-19 16:43:03 LOG: 00000: duration: 0.246 ms
LOCATION: exec_simple_query, postgres.c:960
2005-04-19 16:43:03 LOG: 00000: statement: rollback; begin;
LOCATION: pg_parse_query, postgres.c:464

My question is - are there any "gotchas" I need to look out for -
changes in behavior, etc, that might cause problems with this switch?
The java application makes use of autocommit() quite a bit.

I am running postgresql 7.4.2.

Thanks,

Dennis

This statement is from issuing Connection.rollback() and it will still
happen with the 8.0 driver. The difference is that the 8.0 driver uses
the full V3 protocol which has some logging problems on the server
side, so you just aren't seeing them being executed even though they
are.

Are there advantages of moving to the 8.0 driver?
