Add constraint, index, adapter and query interface names to the list of suggested names in the auto-completion provided in the SQL query console of the Polypheny-UI.

There is an editor component int the UI (src/app/components/editor). It most probably makes sense to add a new method in the backend in Polypheny-DB (webui/src/main/java/org/polypheny/db/webui/Crud.java) which returns a list of all names to names / identifiers to be considered.
