Hi=2C

=20

I'm running a the check_postgres.pl --action=3Dbloat on a database and find=
ing that there is wasted space.

=20

I'm using 95% for the crtical %.  If I use 110% I get the same things=2C bu=
t 115% shows everything is OK.

=20

check_postgres_bloat -H host -p port -db thing -t thing1 -c 95%

check_postgres.pl version 2.14.3

postgres version 8.3.9

I have run a reindexdb on the table=2C full vacuum (fze)=2C still I can't g=
et the wasted size to go down on these=2C so I continue to get critical ale=
rts that my tables are bloated.
=20
check_postgres checks for both index and table bloat.  It looks like my ind=
exes are ok=2C this is just picking up on table bloat.  I'm not sure what I=
 can do to reclaim the wasted space other than vacuum full & analyze.  Mayb=
e a pgdump will do it.

Thanks for any insight=2C
