is it possible to delete the psql log while psql is running?

[Gábor Farkas <gabor@xxxxxxxxxxxxxx>]

hi,

i'd like to delete the postgresql log file
(resides in /var/log/pgsql/postgres),
because it has become too big.

can i simply delete the file while postres is running?

or do i have to stop postgres first, and only delete the logfile after that?

thanks,
gabor
