Subject: vacuuming template0 gave ERROR
To: "pgsql-admin@postgresql.org" <pgsql-admin@postgresql.org>


Guys,

Got the following ERROR when i was vacuuming the template0 database.
postgresql server version is 7.4.5 and stats info in postgresql.conf is

# - Query/Index Statistics Collector -

stats_start_collector = true
stats_command_string = true
stats_block_level = true
stats_row_level = tue
#stats_reset_on_server_start = true

============================

step 1

update pg_database set datallowconn=TRUE where datname='template0';

step 2
\c template0
vacuum analyze verbose
.......
......
INFO: vacuuming "pg_catalog.pg_statistic"
ERROR: could not access status of transaction 1107341112
DETAIL: could not open file "/home/postgres/data/pg_clog/0420": No such
file or directory

step 3
postgres@test1:~> /usr/local/pgsql/bin/psql database1 -c 'SELECT datname,
age(datfrozenxid) FROM pg_database';
datname | age
-----------+------------
template0 | 1112108248
database1 | 1074511487
template1 | 1073987669
(3 rows)

Files in the pg_clog are:-
postgres@test1:~/data/pg_clog> ls -lart
total 417
-rw------- 1 postgres postgres 262144 2005-12-26 02:09 0443
drwx------ 2 postgres postgres 96 2005-12-26 02:17 ./
drwx------ 6 postgres postgres 640 2005-12-26 03:22 ../
-rw------- 1 postgres postgres 163840 2005-12-26 03:23 0444

Problem: template0 is not getting vacuumed due to the above ERROR.. please
let me know whats the solution.
