Naturally: there is no such table, regardless of case.

Not with the SQL you provided:

neilc=# select "BEDRAG" from sancties;
ERROR:  relation "sancties" does not exist

This behavior is intended, although it is true some people find it 
confusing. The logic is:

- identifiers specified without double-quotes are folded to lower case
- identifiers specified with double-quotes are not case folded

So your DDL creates a table called SANCTIES since the table name is 
double-quoted, whereas "SELECT * FROM SANCTIES" is actually looking for 
a table called "sancties". See here for more info:
