In our DB we create partition table for each month (our naming convetion is follow , and I would like to create trigger that insert data to appropriate partition table accounting.cdr_y2009m05, accounting.cdr_y2009m06 etc..). What is the best solution to create such trigger? I can create trigger function as follow: CREATE OR REPLACE FUNCTION partitionig_test RETURNS TRIGGER AS $$ BEGIN IF NEW.effective_date>=DATE '2009-05-01' and NEW.effective_date<DATE '2009-06-01' THEN INTO accounting.cdr_y2009m05 VALUES (NEW.*); ELSE IF .... ................................... but in such solution every month I have modify trigger to handle new month (during import I have to remember about archive months). Second solution is to create dynamic SQL query, but every call of partitionig_test I have to build long string - accounting.cdr_* table has 50 columns. Maybe you know third solution, most elegant ?
