 Determines whether `ANALYZE` collects statistics for readable PXF tables. If true, an analyze
operation on a readable PXF table estimates the number of tuples in the table, generates a
sample table and runs statistics queries on the sample table to calculate statistics, as it
does for native tables. When false, `ANALYZE` displays a message to warn that it is skipping
the table because `pxf_enable_stat_collection` is off.
