Description

Iceberg tables do not support partition-grained refresh, hence

REFRESH iceberg_tbl PARTITION(...)

is not supported.
The current error message is not descriptive:

ERROR: AnalysisException: Items in partition spec must exactly match the partition columns in the table definition: iceberg_tbl (1 vs 0)

We should have a better error message that just says something like 'Partition-grained REFRESH is not supported for Iceberg tables.'
