细节
注：入库时 ON CONFLICT(key) 默认为id或通过如下sql查出来的第一个值select column_names from(
select
t.relname as table_name,
i.relname as index_name,
array_to_string(array_agg(a.attname), ', ') as column_names
from
pg_class t,
pg_class i,
pg_index ix,
pg_attribute a
where
t.oid = ix.indrelid
and i.oid = ix.indexrelid
and a.attrelid = t.oid
and a.attnum = ANY(ix.indkey)
and t.relkind = 'r'
and t.relname like '%'
group by
t.relname,
i.relname
order by
t.relname,
i.relname) as res
where table_name = 'table_name';
