Is there a possibility to disable auto analyze if we set autovacuum_analyze_scale_factor to 100% and autovacuum_analyze_threshold = 0?
Thanks,

The docs opinion:
https://www.postgresql.org/docs/10/static/sql-createtable.html
"autovacuum_enabled, toast.autovacuum_enabled (boolean)
Enables or disables the autovacuum daemon for a particular table.
If true, the autovacuum daemon will perform automatic VACUUM and/or
ANALYZE operations on this table following the rules discussed in
Section 24.1.6. If false, this table will not be autovacuumed, except to
prevent transaction ID wraparound. See Section 24.1.5 for more about
wraparound prevention. Note that the autovacuum daemon does not run at
all (except to prevent transaction ID wraparound) if the autovacuum
parameter is false; setting individual tables' storage parameters does
not override that. Therefore there is seldom much point in explicitly
setting this storage parameter to true, only to false.
