Some times we experience the vacuum being started to prevent wraparound, i understand this will always take place if required regardless of autovacuum settings ?
Is there any way of making the table 'read only' so its nice and tidy / immutable ?

We have many large tables which contain static historical data, they are auto vacuumed on a regular basis (sometimes to prevent wraparound) which i suspect causes a few annoying side effects:- Additional WAL file generation- Increased 'changed' data as far as our online rsync based backups are concernedIs there any way to tell Postgres that these tables are now not available for changes so we can avoid these seemingly pointless maintenance tasks ?ALTER TABLE table_name SET (autovacuum_enabled = false);
