Cannot create multi-tables within the same transaction

I'm testing the CLARUS proxy using the dataset provided in the repository `benchmarking`.
For now i'm focusing on simple tasks, creating the database, the table structure and insertion of some data.

I'm using the version `1.2-snap-ok` tagged in all repositories
I'm using the security policy [patient_anonymisation.xml]( https://github.com/clarus-proxy/benchmarking/blob/master/REQ-NF_PERF/clarus/securitypolicies/patient_anonymisation.xml)
I'm using the dataset [table scheme](https://github.com/clarus-proxy/benchmarking/blob/master/dataSets/ehealth/std/eHealth_tableScheme.tpl) for the table creation
and the dataset [table data](https://github.com/clarus-proxy/benchmarking/blob/master/dataSets/ehealth/std/eHealth_tableData.tpl) for the data insert.

Here is my test:
```bash
$ PGPASSWORD=password PGUSER=postgres psql -h localhost -c "CREATE DATABASE clarus;"
CREATE DATABASE
$ PGPASSWORD=password PGUSER=postgres psql -h localhost -p 5433 -f dataSets/ehealth/std/eHealth_tableScheme.tpl clarus
CREATE TABLE
CREATE TABLE
CREATE TABLE
CREATE TABLE
CREATE TABLE
CREATE TABLE
CREATE TABLE
CREATE TABLE
$ PGPASSWORD=password PGUSER=postgres psql -h localhost -f ./dataSets/ehealth/std/eHealth_tableData.tpl clarus
BEGIN
psql:./dataSets/ehealth/std/eHealth_tableData.tpl:91: FATAL: Record creation not supported by this CLARUS proxy
psql:./dataSets/ehealth/std/eHealth_tableData.tpl:93: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
psql:./dataSets/ehealth/std/eHealth_tableData.tpl:93: connection to server was lost
````

The Clarus proxy output a stacktrace:

When i tried to inspect the database I can see that the database has been created but not the tables.
