I am new to postgres and I have 4 doubts.
1) I have a performance problem as I am trying to insert around 60 million rows to a table which is partitioned. So first I copied the .csv file which contains data, with COPY command to a temp table which was quick. It took only 15 to 20 minutes. Now I am inserting data from temp table to original table using insert into org_table (select * from temp_table); which is taking more than an hour & is still inserting. Is there an easy way to do this?
2) I want to increase the performance of database as I find it very slow which has more than 60 million rows in one table. I increased the shared_buffer parameter in postgres.conf file to 20000 but that does help much.
2) I have partitioned a parent table into 100 child tables so when I insert data to parent table, it automatically inserts to child table. I have followed http://www.postgresql.org/docs/8.1/interactive/ddl-partitioning.html. When I did this, I noticed that when I viewed data of parent table, it had the rows of the child table and is not empty. But the child tables do have the rows in it. I dont understand.
Thanks in advance.
