Hi,
I've created a table with 1000 partial indexes. Each one matches
exactly one row based on the predicate WHERE id = <value>.
However, when I perform an UPDATE of a single row in a transaction,
I've noticed that all those partial indexes show up in pg_locks with
RowExclusiveLock.
Only 2 of those indexes have a reference to the row: the primary key
and a single partial index.
Is it necessary for a partial index that doesn't include the row to be
involved in locking?
Thanks
Thom
