If you can run ps as an OS user, surely you can query the master
instance for the same information, like that for example:
=# SELECT pg_current_xlog_location(),
pg_xlogfile_name(pg_current_xlog_location());
 pg_current_xlog_location |     pg_xlogfile_name
--------------------------+--------------------------
 0/3000888                | 000000010000000000000003
(1 row)
=# SELECT write_location, pg_xlogfile_name(write_location) FROM
pg_stat_replication;
 write_location |     pg_xlogfile_name
----------------+--------------------------
 0/3000888      | 000000010000000000000003
(1 row)
(ps displays the write location for WAL receiver processes)

Note that this is not a bug, this question is more adapted to
pgsql-general for example.
