CommandType means to use select, insert, update, delete and utility
as the categorization to display the counters? I think I am not getting
your point correctly.
Apart from the above, here are the following list of command tags that
are generated in the code, I took only the first word of the command tag
just to see how many categories present. The number indicates the
subset of operations or number of types it is used. Like create table,
create function and etc.
insert
delete
update
select (6)
transaction (10)
declare
close (2)
move
fetch
create (37)
drop (36)
Alter (56)
import
truncate
comment
security
copy
grant
revoke
notify
listen
unlisten
load
cluster
vacuum
analyze
explain
refresh
set (2)
reset
show
discard (4)
reassign
lock
checkpoint
reindex
prepare
execute
deallocate
we can try to pick something from the above list also for main
categories and rest will fall under
other.
