I'm having a problem with pg_autovacuum against both 7.3.2 and 7.4.1 on Redhat 9 and Fedora Core 1. I'm using pg_autovacuum from 7.4.1, everything comes from the postgresql.org RPMs.
If the number of tuples is sufficiently high, pg reports 'reltuples' back in TABLE_STATS_QUERY in scientific notation instead of an integer. Example: 4.35351e+06 instead of 4353514 pg_autovacuum then uses atoi() to reach the incorrect conclusion that there are 4 tuples. Obviously, if that table gets more than a couple of updates, it gets vacuumed a bit too often. :) Changing from atoi() to atof() solves the problem completely. new_tbl->reltuples = atof(PQgetvalue(res, row, PQfnumber(res, "reltuples"))); new_tbl->relpages = atof(PQgetvalue(res, row, PQfnumber(res, "relpages"))); I'm not sure how I can be the only person running into this. :) ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
