1. with temporary file...
ok I've made the file (it likes good as I can see from size)
====================================
% pg_dump -d
BaseA --port=54321 --host=localhost --table=TableA --data-only -v -F
c -f ./idstation.backup
====================================
but pg_restore dont want make its work...
====================================
% pg_restore --dbname=BaseB --no-owner --table=TableA -v ./idstation.backup
pg_restore: connecting to database for restore
pg_restore: implied data-only restore
====================================
also games with options --single-transactions, --clear, --data-only dont help
me - as result - <BaseB.TableA> has old data...
2. pipe to psql...

I do
% cat ./idstation.backup | psql -d BaseB
and get errors about primary key unique constraint violation...
I cant delete records from <BaseA.TableA> because this table have references
from another tables...
Im sure, that it is not a bug in pg_restore, but in my head... please help me
debug it
