Aren't there some difference in crawling logics between MySQL and PostgreSQL?
I did some tests on web crawling using both of MySQL and PostgreSQL. MCF0.5 running on MySQL indexed around 6000, and meanwhile MCF0.5 running on PostgreSQL indexed over 12000 documents. MCF0.6 running on MySQL indexed around 6000. MCF0.4 running on PostgreSQL indexed over 12000 documents. Each number of indexed documents above is a result of first crawling after deleting indexing history from DB. It seems that changing DB affects crawling and indexing.
