Hello, I'd like to postpone an "autovacuum: VACUUM public.mytable (to prevent wraparound)" and handle it manually at another time. I thought I could set these storage parameters on the large table in question ("mytable") like this:
ALTER TABLE mytable SET (
autovacuum_freeze_min_age=10000000,
autovacuum_freeze_table_age=800000000,
autovacuum_freeze_max_age=1000000000
);
then kill the running autovacuum process, but unfortunately it just keeps coming back:
mydb | 22734 | 05/26/2015 23:29:10 | autovacuum: VACUUM public.mytable (to prevent wraparound)
I also tried setting the toast.autovacuum* storage parameters, as well as a postgres reload, but neither made any difference.
Here is the table's age:
mydb=> select age(relfrozenxid) from pg_class where oid = 'mytable'::regclass;
age
-----------
203065951
(1 row)
So 203 million, which is just past the 200 million default (which is why I started looking at this). But it's less than the 1 billion I set the storage param to.
Here is \d+:
mydb=> \d+ mytable
Table "public.mytable"
Column | Type | Modifiers | Storage | Stats target | Description

(removed al lthis)
Options: autovacuum_freeze_min_age=10000000, autovacuum_freeze_table_age=800000000, autovacuum_freeze_max_age=1000000000, toast.autovacuum_enabled=false, toast.autovacuum_freeze_min_age=10000000, toast.autovacuum_freeze_table_age=800000000, toast.autovacuum_freeze_max_age=1000000000
I'm guessing I'm missing something here, can anyone offer suggestions or ideas on what I should try next?
Here is my version:
mydb=> SELECT version();
version
---------------------------------------------------------------------------------------------------------------
PostgreSQL 9.3.4 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-44), 64-bit
(1 row)
Thanks!
