You need to include "%u" in the log_line_prefix setting in your postgresql.conf. Like this:

log_line_prefix = '%m %d %h %u '
#log_line_prefix = '' # special values:
# %a = application name
# %u = user name
# %d = database name
# %r = remote host and port
# %h = remote host
# %p = process ID
# %t = timestamp without milliseconds
# %m = timestamp with milliseconds
# %n = timestamp with milliseconds (as a Unix epoch)
# %i = command tag
# %e = SQL state
# %c = session ID
# %l = session line number
# %s = session start timestamp
# %v = virtual transaction ID
# %x = transaction ID (0 if none)
# %q = stop here in non-session
# processes
# %% = '%'
# e.g. '<%u%%%d> '

Also 9.1 is pretty old. You should think about upgrading as soon as is practical.

Dear Expert,

May you please provide the solution for below query.

I have to create a log for all the update query executed in database along with its username who has executed that query.
However, I am able to log all the update queries in my pg_log file but it’s not showing particular user who has run the query.

I am using PostgreSQL 9.1 with Linux platform.
