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. :)
