Though, it doesn't yet do the trick. I get the following warnings on 

PSQL ERROR: index "semi_pred_lex_id" does not exist
CONTEXT: SQL statement "DROP INDEX semi_pred_lex_id CASCADE"
PL/pgSQL function "semi_drop_indices" line 3 at SQL statement
SQL statement "SELECT semi_drop_indices()"
PL/pqSQL function "semi_setup_pre" line 2" at perform

ERROR: Attempt to throw to the non-existent tag :SQL-ERROR

As a result, loading complains with:

WARNING: no lexical entries indexed for generator

Any ideas?



In case this is related: I do get error messages concerning "no 
semantics and no filter rule"  for some entries, as well as occasional 
complaints about underdetermined PRED's. I know I should filter these 
out, or specify the missing PRED....
