On Linux at least - not sure about Windows - deleting a file does not remove it from the file system until there are
nomore processes holding the file open.<br /> So while postgres holds the file open, it can keep writing to it
happily.<br/> You won't be able to see the file in the directory, and the space won't be freed. You can find such
thingswith the "find"command by looking for files with a link count of zero.<br /><br /><br /> On 10/15/2010 11:03 AM,

obviously..what else?.<br /><br /> Is there any way to check within Postgres what the current log name (with a
particulartime stamp when rotated last time) is so that a file with a correct  matching name can be manually
created?<br/><br /> For this situation, what is the proper way to get the server to write to a new log file without
havingto bounce the Postgres server itself?<br /><br /> Thanks!<br /><br /><br /></div><br /></blockquote><br /><br
