Supabase is configured with a maximum of 4 logical replication slots

If I have hundreds of client users, but this logical replication only supports 4 (as implied by the default max_wal_sendersor max_replication_slotsvalues), how would I use it? Or do I use powersync server to manage concurrent data access for clients?

A PowerSync instance uses a maximum of two logical replication slots, so the 4 on Supabase is sufficient for most use cases.

PowerSync essentially replicates a copy of the data as defined by your sync rules, optimized for syncing and then users sync from that - it does not directly connect to your source database for each user.
