So this is a big query? Somebody reported this error when IO is intensive.
To conclude the reports we have received:

(1) If IO is intensive (no matter you have anti-virus software or not),
you may encounter "invalud argument" error;

(2) In some cases, anti-virus software could cause "invalid argument"
error;

(3) You may encounter "permission denied" problem (no matter you have
anti-virus software or not) in some unknown condition;

Unfortunately we haven't found out the cause of this problem ... I am
thinking an urgent need is let PG print the GetLastError() for Windows
version as well.
