Syndesis doesn't show PostgreSQL demo data procedures

When I select PostgresDB connection (created when demoData: true) and Invoke stored procedure step, there are no procedures in the dropdown, even though the DB contains it:
```
sampledb=# \df sampledb.*
List of functions
Schema | Name | Result data type | Argument data types | Type
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
sampledb | add_lead | void | first_and_last_name character varying, company character varying, phone character varying, email character varying, lead_source character varying, lead_status character varying, rating character varying | func
sampledb | create_lead | SETOF record | OUT first_name text, OUT last_name text, OUT company text, OUT lead_source text | func
(2 rows)
```
There are no related error in the server/meta pod.
I have tried to create another function manually ( https://github.com/syndesisio/syndesis-qe/blob/1.12.x/rest-tests/src/test/resources/features/integration-database.feature#L37 ) but it didn't show up either.
