permissions - Reshift grants verification HAS_TABLE_PRIVILEGE fails -

i'm fighting redshit grants groups, schemas, default privileges. when try check correct using has_table_privilege

select tablename,     has_table_privilege('analyst', tablename, 'select') select,    has_table_privilege('analyst', tablename, 'insert') insert,    has_table_privilege('analyst', tablename, 'update') update,    has_table_privilege('analyst', tablename, 'delete') delete,     has_table_privilege('analyst', tablename, 'references') references  pg_tables schemaname='datalab' order tablename 

i :

an error occurred when executing sql command: select tablename,     has_table_privilege('analyst', tablename, 'select') select,    has_table_privilege('analyst', tablena...  [amazon](500310) invalid operation: relation "dss__transaction" not exist;  execution time: 0.2s 1 statement failed. 

what hell happening here ?

i tried , query failed on first result pg_tables. in case because needed explicitly state schema each table in. worked me:

with cte  ( select schemaname+'.'+tablename table_name pg_tables schemaname = 'datalab' ) select table_name,     has_table_privilege('analyst', table_name, 'select') select,    has_table_privilege('analyst', table_name, 'insert') insert,    has_table_privilege('analyst', table_name, 'update') update,    has_table_privilege('analyst', table_name, 'delete') delete,     has_table_privilege('analyst', table_name, 'references') references  cte order table_name asc;
