Report generation fails sometimes/often due to missing end-pg_stat_user_tables.csv or end-pg_stat_user_indexes.csv

[Krysztophe]

About halt the time, the report generation fails with this error: FATAL: can't read file pgcluu_output_dir/./end-pg_stat_user_indexes.csv: No such file or directory

I can create the file with touch and I get then: FATAL: can't read file pgcluu_output_dir/./end-pg_stat_user_tables.csv: No such file or directory

Another touch and I get my report, of course with 'Tables statistics' and 'Indexes statistics' missing.

I haven't really understood why and how it fails yet, but it's painful. Any idea?
