There's a bug in pg_autovacuum that makes it vacuum large tables way to
frequently.
ogr=# select reltuples from pg_class where relname='ogr_summary';
reltuples
-------------
2.64411e+07
(1 row)
[2004-04-27 02:03:08 PM] table name: ogr."public"."ogr_results"
[2004-04-27 02:03:08 PM] relid: 615097; relisshared: 0
[2004-04-27 02:03:08 PM] reltuples: 7; relpages: 519951
[2004-04-27 02:03:08 PM] curr_analyze_count: 9904180; cur_delete_count: 168282
[2004-04-27 02:03:08 PM] ins_at_last_analyze: 9904180; del_at_last_vacuum: 168282
[2004-04-27 02:03:08 PM] insert_threshold: 507; delete_threshold 1014
[2004-04-27 02:03:08 PM] added table: ogr."public"."ogr_results"
I suspect the issue is on line 121:
new_tbl->reltuples = atoi(PQgetvalue(res, row, PQfnumber(res, "reltuples")));
I'm not a C coder, but doesn't atoi just take a text value and convert
it to an int? Shouldn't all the stats counters be stored as reals?
