The driver included in 6.5.3 is actually the 6.5.2 one (due to me not
committing it correctly).

In the 7.0, the transactionIsolation() code was implemented as part of the
javax.sql extensions.

Subject: [INTERFACES] Default mode for transaction in postgreSQL and
JDBC

Hello,

I played around with the transaction management in postgreSQL and I found
that the JDBC-Driver allways indicates that the transaction isolation
level is "serializable". This is hard coded within the source and changing
the transaction isolation level with the provided method gives an
exception. So far so good.
A second look in the postgreSQL source code (V 6.5.3) indicates that the
default isolation level is read commited, the documentation states the
same and a check with psql confirms this.

So, is the transaction isolation level within my (6.5.3) JDBC-Version
really serializable?

Regards
Dirk
