Hm ... we've heard one previous report of pg_stat_statements' query text
file getting unreasonably large, but it's not clear how that can come
to be. Do you have a lot of especially long statements being tracked
in the pg_stat_statements view? Are there any other signs of distress
in the postmaster log, like complaints about being unable to write
pgss_query_texts.stat?
