I'm implementing savepoint support for the JDBC driver and I'm seeing an 
assertion failure in cvs head this morning.  It seems related to using 
both savepoints and the v3 protocol.

LOG:  statement: create table savepointtable (id int primary key)
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index 
"savepointtable_pkey" for table "savepointtable"
LOG:  statement: BEGIN
LOG:  statement: INSERT INTO savepointtable VALUES ($1)
LOG:  statement: SAVEPOINT JDBC_SAVEPOINT_0
LOG:  statement: INSERT INTO savepointtable VALUES ($1)
ERROR:  duplicate key violates unique constraint "savepointtable_pkey"
LOG:  statement: ROLLBACK TO SAVEPOINT JDBC_SAVEPOINT_0
TRAP: FailedAssertion("!(portal->resowner == ((void *)0))", File: 
"portalmem.c", Line: 694)

Note the line number in the error message appears accurate, but doesn't 
exactly match that in the stacktrace.  This is the same as the last time I 
reported a problem of this type.  I got them to match by building with a 
different compiler version (which I can do again if necessary).
