Build the read_parquet(...) table expression from one or more file URLs /
globs. A single source renders read_parquet('url'); multiple sources
render read_parquet(['a', 'b']). Every URL is escaped as a string literal.
union_by_name := true and hive_partitioning := true are set so mixed
schemas across a hive-partitioned Overture theme line up by column name.
