PostgreSQL 9 'pgstats wait timeout' problem I'm asking about this here because in the PostgreSQL mailing lists no one answered me.
In one of my servers (Windows 2008 R2 Standard/PostgreSQL 9.0.5 64 bits) the logs are being flooded with the following message:

2012-03-26 00:00:11 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:19 BRT AVISO:  pgstat wait timeout
2012-03-26 00:00:31 BRT AVISO:  pgstat wait timeout


I checked other threads in the PostgreSQL mailing lists that were answered, but there are no definitive answer. Some speculate about I/O overload, but I don't think it would cause this message to be logged almost all the time that the server is up.
Do you, that use the combination of Windows+Postgresql, have ever had this problem? If yes, were you able to fix or identify the problem?

Thanks
Reloading the config makes the errors go away, and performance improves (and db statistics start getting recorded again).

I've set up a Windows Scheduled Task which performs a pg_ctl reload -D"insert here the address of your pg directory" on the hour (we're running an incredibly busy application). Hacky, but it's working.
