Hello, I have a table with 29268 odd records. Deleting records is VERY slow, and I don't know why.
I explained analysed the following query: delete from people where id < '2000' Index Scan using people_pkey on people (cost=0.00..71.68 rows=2792 width=6) (actual time=1.361..5.657 rows=2000 loops=1) Index Cond: (id < 3000) Total runtime: 13.006 ms 3 row(s) Total runtime: 63,869.322 ms using phppgadmin (it's also slow via command line or Perl/DBD). I haven't optimized postgresql yet (kernel.shmmax, etc), but I don't see why it is taking this long. Why is it 13ms, and then 63869ms? There is 1 fkey relationship, and it is primary key to a few other (now empty) tables. The fkey's are on update cascade on delete restrict. Deletes on other tables are quick. Any ideas?
