As a side not, one more thing.
Since you mentioned that corruption happened in Windows environment,
I'd suggest that Postgres data directory should be excluded from being scanned by whatever anti-virus software you have
runningon that system (I suspect there is one). Scanning PG data directory by anti-virus software could reduce
performanceand also in "severe" cases - corruption.
