IO Error: buffer_ptr not set in CheckHeader

[cobolbaby]

What happens?

Using DuckDB to export a PostgreSQL table to a Parquet file, if the table in PostgreSQL is a view, you may encounter the following error IO Error: buffer_ptr not set in CheckHeader. I haven't figured out the exact reason yet.

To Reproduce

COPY (SELECT * FROM {POSTGRES_DB}.{POSTGRES_SCHEMA}.{table_name}) TO '{table_dump_file}' (FORMAT PARQUET, COMPRESSION ZSTD, ROW_GROUP_SIZE 100000);

OS:

x86_64
