Hi,
assuming a constraint is added to a table as NOT VALID. Now I know it IS
valid. Can I simply declare it as valid by
update pg_constraint
set convalidated='t'
where conrelid=(select c.oid
from pg_class c
join pg_namespace n on (n.oid=c.relnamespace)
where c.relname='tablename'
and n.nspname='schemaname')
and conname='constraintname';
instead of
alter table tablename validate constraint ...
Or does the latter have other side effects?
I am asking because I want to avoid the ACCESS EXCLUSIVE lock required
by the ALTER TABLE. I am sure there are no rows violating the constraint.
Thanks,
Torsten
