pg_time, pg_log growing without limits

Hi,

	I use version 6.2.1 currently, and I have a problem of pg_time, pg_log
files growing.

	pg_time	->44MB
	pg_log	->2MB

	Is it possible to truncate these files somehow before they exceed the
size of the database?

	Will it work if I just recreate them with 0 size?

Thank you,

About the use of language: it is impossible to sharpen a pencil with a blunt
ax.  It is equally vain to try to do it with ten blunt axes instead.
