I think I found the problem. I was comparing wrongly some values and based on that, every time the script was run (that means once every 5 minutes) my script deleted two tables and populated them with about 70 thousand records.
I'm not sure I understand what you're saying, but if you vacuum at the wrong time that can cause problems. I've shot myself in the foot before now doing something like:
DELETE FROM big_table VACUUM ANALYSE big_table COPY lots of rows into big_table
Of course, the planner now thinks there are zero rows in big_table.
I mean from 5 to 5 minutes DROP TABLE
CREATE TABLE
INSERT 70000 rows in table
I thought you were trying an inserting / updating if it failed? You shouldn't have any duplicates if the table was already empty. Or have I misunderstood?
