Re: [Patch] Use *other* indexes on the subscriber when REPLICA IDENTITY is FULL

Hi,

I also think so. If this is true, how can we think of supporting

I also don't think we can support anything other than btree, hash and brin
as those lack equality operators.

And, for BRIN, Hayato brought up the amgettuple issue, which is fair. So,
overall, as far as I can see, we can
easily add hash indexes but all others are either very hard to add or not
possible.

I think if someone one day works on supporting primary keys using other
index types, we can use it here :p

Thanks,
