Re: Size of pg_multixact/members increases 11355

Dear Thomas,

Thanks for your updation.
I have also checked on older version 8.1.3.
In older version , after 32 MB folder size increased, it automatically
cleaned files and size is reduced.

This size is dependent on which paramter in older version?

Regards,
Yogesh
