fallintoplace opened a new pull request, #1466:
URL: https://github.com/apache/iceberg-go/pull/1466

   ## Summary
   
   - check namespace existence, catalog-object emptiness, and property deletion 
in one serializable write transaction
   - treat views and future object types as namespace contents instead of 
relying on the table-only `ListTables` result
   - keep view-only namespaces intact and return an object-neutral 
`ErrNamespaceNotEmpty` error
   
   ## Why
   
   On the V1 SQL schema, `ListTables` intentionally excludes views. 
`DropNamespace` used that filtered result to decide whether a namespace was 
empty, so a namespace containing only a view could report a successful drop 
while the view row—and therefore the namespace—still existed. The separate 
pre-checks also left the decision outside the delete transaction.
   
   ## Testing
   
   - `go test ./catalog/sql`
   - repository package suite excluding the locally hanging `io/gocloud` test 
binary
