>Summary: TRACE,PROFILE,DEBUG should be impossible for JDBC and ODBC

Initial Comment:
Dear MonetDB Developers,

After my EXPLAIN bug report I have checked the TRACE, PROFILE,DEBUG 
availability for the JDBC client. The result is the same.

Steps to reproduce:
1) Connect the database with mjclient
2) Issue the following queries:

debug select count(*) from tables;
trace select count(*) from tables;
profile select count(*) from tables;

Example scanario:
monetdb-> debug select count(*) from tables;
Error: protocol violation, unexpected line: mdb>#    mdb.start()
monetdb-> trace select count(*) from tables;
Error: protocol violation, unexpected line: breakpoint on select count(*) from 
tables; not set
monetdb-> profile select count(*) from tables;

Connection warning: mdb  Symbol not found
monetdb->

Regards,
B.

details:

mdb is an interactive debugger that should never be started for an
application like connection such as a JDBC connection.  There is no way how
JDBC can deal with an interactive debugger prompt.

The interactive commands you described hence need to be disabled for JDBC
connections.

Thanks for remarking this.
Please use the C-version instead, i.e. mclient

More details will follow.
