i have recently started work with PostgreSQL. Here is my question! i have a table in oracle and i want to insert all record in PostgreSQL, For this i'm using Foreign Data Wrapper for oracle. it work fine with small set of data but as i tried to get large table query got failed after getting 0.5 million records. here is the error "out of memory for query result" can someone let me know how to avoid this. One more question I'm on windows environment. i could not get any Foreign Data Wrapper for oracle for 64bit system. anyone explain this ? lastly i would like to ask when we create a wrapper table where actually it is created. it hold the record in memory or physical table. what is the way if i want to insert all record from Wrapper table to ordinary table regards Adeel Usman -- View this message in context: http://postgresql.1045698.n5.nabble.com/Foreign-Data-Wrapper-out-of-memory-tp5757385.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
